ok the line running from the tank to the engine is leaking. it looks like it is right above the bellhousing. how do i go about replacing the line. i think i need to lower the trans to get to it. does anybody have any tips for me. do the lines connect just above the transfer case and then again at the fpr or is there another connection between there.

please help fast

First off, see if you can pinpoint the leak. A leak at the top of the engine will run down the lines and drip at the low spot; near the bellhousing. I'd check first to see if for some reason, your lines are loose on the regulator. Seems as though the easiest fix would be to cut the metal line off the regulator, leaving an inch or two, the cut it down near your fuel filter, and run fuel injection hose from one to the other, double clamp it, and attach it to the frame rail. Is it rusted out? Not sure where you're located. I've replaced about every metal line on every car I've owned because they all rust out. Fuel injection needs fuel injection hose, not standard $0.99/ft 3/8" hose; I think it's rated up near 60psi and a little spendy.

well here the funny thing that i just noticed about the truck. the damn body mounts rusted out causing the body to drop down an inch and i think that caused the lines to rub on the body. damn i hate rust, i saw that last fall when i was looking for a clunck. i was going to fix it this spring when i had some money. im not exactly sure this is the problem because i havent got the lines out yet but i think thats what happened. i will hopefully have the lines out tonight and know for sure.

ok got the transfer case out the the fuel lines disconnected. i think i need to pull the trans because the lines dont want to come out. i want to run steel braided lines from the fuel filter to the fpr and also the return line. does anybody know what size lines and what adapters i would need. also can you cut steel braided lines with a hacksaw or what should i use, ive never messed with this stuff so i dont know. well the good news in all of this is i will finally put my adjustable fpr on and quit blowing it off.

you should be able to do this without pulling the trans....if the truck is stock, there are a couple of clips that keep the lines in their place....one should be bolted to the back of the driver's side head and the other should be on the driver's side of the tranny (way up there)....sounds like you got the third one (bracket) on the transfer case...what i would do it remove the body mounts (since you need to replace them anyway) and jack the body up as high as necessary to do the job....then replace the rusted mounts while you're at it.....if you're set on braided lines, just take your lines to a hydraulic hose/fitting shop and have them get you what you need...make sure it's fuel line as mentioned before...try aeroquip and ask about reusable fittings....get extra feet as it might be easier to slightly reroute the new lines for them to fit well....good luck and it sounds like you busted your ass tonight....

Re: fuel line question help ASAP

I think your in the right direction by replacing them with braided line. I wouldnt go as far as taking the whole trans out unless it doesnt bother you to. you could of slid the trans back with the transfercase still bolted up and probably had plenty of room to get between the trans and the block to do the new lines. goodluck

Someone does need to make a braided fuel line diagram with all the correct AN fitting sizes and part numbers and such. Tommyquest? volunteer's?

I use #6 line and earls makes adaptor fitting to go from the fuel filter to a #6 and from the fuel rail to a #6. they are power steering adaptors with an oring to make the seal just like the stock ones do.

with as many frame-off rebuilds going on right now, that could be very easy for someone to do....how about jjorgenson, the guy that just powdercoated his frame? i've completed 2 body-off syty jobs so far and can tell you from my most recent experience (syclone) that larger diameter fuel hose/line doesn't fit as well between the body and the tranny as do the stock lines.....that's why i mentioned above that "rerouting" larger outside diameter lines should be considered.....

Re: fuel line question help ASAP

do you need to use teflon tape or any other sealants on the fittings. also how do you cut the lines and attach the fittings. i finally got my parts today. i'll post part numbers if anybody needs them.

Re: fuel line question help ASAP

I never used teflon or any sealant. Just snug it tight, start the truck and look for leaks.
