I plan on running all new hard line also. I have bent and spliced together 4' pieces with rubber fuel line hose but never bent entire coil in one run, this may turn out to be a nightmare. Any tips or should I stick to the 4' pieces connected with rubber fuel line(The half ass way I know). I will do as BR[] said and plug one side and test for a leak first only to reassure my self I need to replace the entire line, and I'm no artist so I'm not too worried about looks underneath car. Definitely verify that the hard line is leaking before undertaking the task of replacing it. As Postcar suggests, if you do have to replace it, I'd use aluminum line. In my opinion, there is not way you can rerun steel line the full length with the body still on the car without kinking it up so bad that it'll be worse than what you take out. You could unbolt all of the passenger side body mounts, and raise the body up a good bit from the frame to gain access, but I think you will opening up a can of worms, unless you're planning to replace body bushing anyway, or have done that in the recent past. The biggest challenge in replacing the fuel line with the body on the car is routing over the rear axle. There is very little clearance there, and don't be tempted to take a short cut... you want to keep the line out of harms way from potential road debris.

Before this thread gets lost in the weeds
I was reading thru "Re: Disappearing Fuel" thread this morning knowing Xtremejr would be crawling under his car this weekend, not wanting him to experience any more bumps to his head than need be, I wanted to see if anything more could be added to help him out. While reading it occurred to me, this is a nice thread. A lot of information was gathered, there was more than average participation, All in all, the way a thread should progress. Granted there were a few touchy moments, but just typical car guy stuff. Things got back on topic, everyone returned, and info flowed. One other point I`d like to make. When giving advise it`s common to omit information because it`s considered common knowledge. The lamest comparison I can think of, would be, if a member asked what to do if one of his parking lights didn`t light, he noticed that after removing the lens, and looking thru the glass of the bulb, one of the elements was burnt. I guess a common reply would be, pick up a new bulb ! Should that be the end, or should a person go on to include, remove old bulb and discard, install new bulb (using proper dielectric grease) finally install lens cover. My Bla-Bla-Bla, comes down to this. Some VERY important information came out at the last minute !
KUDOS to mongoose !! The dragsta vert guy.
"The biggest challenge in replacing the fuel line with the body on the car is routing over the rear axle. There is very little clearance there, and don`t be tempted to take a short cut... "
This info, on it`s face, is elementary. But is a critical step in the procedure. Without being insulting, I believe mongoose informed as to the importance of the routing of the fuel line in this area. Safety for sure, but this is also the anti siphon trap in the fuel line. (Same principal as the gas tank vent trap), but also protects against fuel being siphoned to the crankcase should your pump diaphragm fail, and holds fuel in the line forward of it`s rise for prime. I`m usually the first to jump on bad info, this was good, and I couldn`t pass it up.

So one way filter anti drain back filter arrived today, I'm going to call the previous sentence Plan B. First things first, replace all flex line with new. that don't work test all hard line for leaks and only replace that section. if that don't work replace all hard and flex line. if that don't work which it should, then Plan B.

Ok guys so i just finished replacing all fuel lines. Heated all fittings and clamped them all down tight. still had to start on a bottle of gas. reconnected to fuel line and she ran great till i shut it off then she didn't want to refire even if i held gas pedal to the floor. I'm puzzled I had put a lot of time into all of this and nothing. I mean its ok I will just have to try something else but really. I also replaced plugs, when I got her fired up she was back firing a lot. maybe a problem with timing? ??

I'm reading two things here... ...she ran great till i shut it off... ...when I got her fired up she was back firing a lot. So I'm confused as to the running condition. Or perhaps you're saying when you initially start it it's running good... then once you attempt to restart it, it runs rough. So it's hard to tell which rabbit trail to start running down next. What did the testing reveal per Postcar's, Ramz's and Bro's suggestions. Were you able to isolate anything? Did you replace all the rubber and hard lines, or did you find that the hard lines are ok? After the replacement are you still seeing the lack of fuel in the supply lines? If it's running ok the first time you get it going, but then bad or not at all once you try to restart it, I'm not sure I would consider bad gas, or the timing being off... but have you check it, just to see? If you can get it to run with a rubber hose directly from the fuel pump inserted into a container of gas... and restart it several times with no issues, then you focus probably needs to remain with the fuel system. I am far from an expert here... no background, training, career in the automotive industry whatsoever. Just a "neighbor" with an old car or two stopping by with a cup of coffee in my hand. Hopefully I provided a bit of help.

I also replaced plugs, when I got her fired up she was back firing a lot. maybe a problem with timing? ?? Ok, I have a few questions, You say once you got it started with a bottle of fuel and reconnected the fuel line it ran good. After shutting it off it wouldn't restart> or was hard to restart. During your attempts to restart it did you check to see if you had fuel? Was it perhaps flooding or did you not have fuel. Did you try to restart it immediately after shutting it off, if so you should have had fuel in the bowl which is plenty for a restart. Sounds to me like you might also have a flooding situation on your hands. You also stated that after replacing the plugs it started backfiring, if that happened to me I would think that I screwed up and maybe mixed the plug wires up and I would get the book out and recheck to see if I had the plug wires on correctly. Try not to get frustrated on your quest to get your car running. I don't know what kind of cars you grew up working on but these are at best crude compared to what we purchase now but are basically simple compared to modern cars. It sounds like you are willing to forgo the frustration to figure one of these babies out and one day you'll get it.

What I meant to say is That I had got it fired up on a bottle of gas cause I replaced all the flex lines and replaced all the front half of the hard line. The remainder of hard line I inspected really well. After reconnecting to fuel line it was really hard to start even with the pedal to the floor it would just sputter and sputter, so I went out and bought new plugs, something cheap to try. after changing plugs I got her to fire without the bottle and it was backfiring a lot, I'm guessing from holding pedal to floor and being starved from fuel at same time, about 30 minutes later I tried again and got it fired again without the bottle it ran about 10-12 minutes, shut it off and it wouldn't refire. I'm gonna drain all the gas today and get new today and look into possible flooding due to throttle linkage being set high/allowing too much fuel is something I could have over looked when installing new carb. Plug wires are all correct, i changed one at a time knowing I didn't want that problem. gonna keep plugging away and get this thing figured out sometime.

Ok, more questions to ask. I reread your first post and it states you added a new fuel pump and holley carb. Question one is what kind of pump did you buy and how many PSI of pressure dose it put out. Should state on the instructions or box if you have them. If it puts out more than say 6 lb's of pressure it could be flooding the carb due to overpressure overriding the float seat. Question two is did you adjust the holley float level's. I personally have never had a holley float set too high right out of the box but that doesn't mean it can't happen. After the car has run immediately look down the carb without touching the throttle plate and see if their is any gas dripping, if there is that is the first thing that needs to be corrected.

All the hard line, half the hard line, ran great, backfired from being gas starved. I put tab "A" in to slot "C", I know the instructions say slot "B" just thought I`d take a short-cut. Any ideas on a quick fix

The pump has no p/n or name or even specs, however when I hooked a vacc gauge to it she read out to 15-20 cm hg or (6-7in hg vacc) at the pumps inlet. At the pumps outlet she tops out at 7psig after cranking for about 10 seconds. Outlet pressure drops to zero about 1 min after sitting. I did not adjust floats, whats a standard adjustment as an example (tighten nut all the way down and back off 3 turns). Or do I have to run and check and so on and so fourth.

I was in the garage this morning looking for something to do, decided to take a fuel pump off of one of the 425`s. I knew the last engine I removed from the car had a decent pump since it ran the engine fine. Pulled the pump, clamped it in the vise, hooked a vacc. gauge to the suction side, three pumps to get 15hg, removed the gauge and plugged it in the discharge side, 3 pumps to get 5lb., at 5lb I heard the return open up and the pump effort was noticeably decreased. So, with the crank, cam ratio you only need to turn the engine 6 revolutions. During the 3rd. stroke on the supply side of the pump as the gauge was approaching 15hg. I noticed the rubber hose I was using starting to egg shape, and the effort needed to stroke the pump noticeably increase. Did yo even bother to read the post I made telling you 6 REVOLUTIONS ?? O.K., then lets try it this way WARNING ! WARNING ! Do not turn engine more than 6 revolutions, it is possible, on the vacuum side, TO SUCK THE SNOT OUT OF YOUR PUMP !!

Those are all of the different problems I was encountering while trying different ideas. After putting over 20 hrs of my weekend into this problem your head tends to jumble everything together. Any way I found a leak In the line. The only reason I had found it was My dad came over when I was looking over the line for the second time. he disconnected the line before the pump and blew low pressure air into the line which created a siphon and with pressure from line being full of fuel finally the fuel started to leak out above axle, I will have to wait to fix since I have to work 65 hours this coming week. I tried to provide you guys with as accurate of info I could at the time of each issue when I get frustrated my head gets going every which way but forward. who knows maybe the leak is just the start of isolating the problem. For everyones sake I hope not.

well the way I look at it by next weekend the problem should be fixed and I will move on with a hell of a lot more knowledge than I started with or their is always "a match and a gallon of gas" if the problem dosent get fixed. With my luck my dad created that hole when he blew compressed air in the line, but I hope not.

Match and a gallon of gas, things we say when frustrated. Yeah she starts good even after sitting for a few days. Haven't started for about a week, Ive been nursing away some pulled muscles and/or broken ribs after racing go-karts at sugar river raceway in broad head wi.

Good for you (regarding the car now starting) and as far as things said while frustrated? I know better than most how that goes. You`d be surprised how many members are nursing a pulled something or another. Again, glad your up and running again

Thanks and Thanks for everyone else's input with my fuel problem. I now will move on to another problem, soon as I find out what the next issue is cuz they are always right around the corner.
