Ok, I have spent the better part of last night and this morningsearching several boards but nothing much has come out of it.

First the story. I drove home yesterday from work and noticed apuddle behind my car. Look under the car and I see it dripping.Felt it, smelled it, it was fuel. The rupture seems to be right underthe front passenger seat.

I am not sure if its the main fuel line or the return fuel line.

After looking under the car briefly and looking up on boards, itseems that the steel lines are hooked up to rubber hoses onthe two ends. The lines are also packed tightly against thepassenger side frame rail using clamps and stuff.

So what do I do? Just disconnect all the clamps, disconnect thelines from the two rubber ends, drop the line, buy new line, bend it accordingly, and off I go?

Is there anything technical involved? Besides buying a pipebender?

How big are the lines? Is there a certain size? What other optiondo I have? I have considered taping it up temporarily but it'sstill leaking/dripping right now so its hard to get it dry enoughbefore I tape it up.

I think you got it right: Buy line and install. Not sure if the dealer would have a pre-bent line or not.

It will be hard to tape it up if since the glue on most any tape will come apart when in contact with gasoline, plus the pressure of the pump.

Is there anything complicated involved with the removal of theexisting lines?

I mean, from the quick look I had, it doesn't seem to be thatinvolved, but you never know. I need to get this done in the nextfew days so I really can't toy with 'trying' things.

All shops are closed today (Sunday) so I have to wait till Mondaybefore I can get any quotes. How much do you figure it mightcost me just to replace the steel line?

The only hard part I could think of is that it may be a pain to get to the incoming side of the line, which is on the top side of the tank. Honestly, I have not had to do this myself.

Here's an idea: Since there are already some rubber hoses that use hose clamps on the set up, you know that hose and clamp will hold. You can just cut the section of line off where it's broken, and splice on a short piece of fuel hose. I wouldn't do this on fuel systems that are higher pressure and use banjo fittiings and such, but on ours, it should be good.

If you do the splice, make sure to get pressure rated fuel hose and fuel hose clamps, they are a little different than standard hoses and clamps.

I have considered placing a rubber hose in between the cut.

I don't think the rubber hoses on the fuel tank end look all thatcomplicated, although I could be wrong.

I am going to the automotive hardware store right now to seeif I can find the hoses and clamps.

Thanks,

There are two lines you can get access to by taking off the top cover for the fuel sender unit. there's another one, but looks like you need to drop the fuel tank to get access to it, it's also not a standard size so you might have some trouble getting it replaced. Up front there are the three long hoses, two on the fuel filter, and one from the FPR to the hardline. Then there are a few more short sections above the intake manifold.

If you're going to use fuel line, make sure it's the high pressure stuff, 3/8". I used about 8 feet of gates high pressure fuel hose when I redid my fuel lines.

Why do I need to drop the tank? It looks like there are rubberhoses that come from the fuel pump, and then it's all steel linesdown to the front of the car where there are two more rubberhoses hooking up to the lines.

Wouldn't I just disconnect the steel lines from the two rubberlines and then change the steel line?

Iwill talk to a mechanic about only placing a cut out piece wherethe hole is or if the price isnt that big, replace the entire steel line.

no no man, do not drop the tank because i had the same problem and this is how i fixed it.I had ****ty russel hoses and fitting in my car that were way oversized so I got some lines from a doner 240. The two hoses comming out of the tank can be used, just stick the new steel lines in them and put a hose clamp over it. next you have to connect the front up same way. main line is with the fuel filter.the new lines in the back have to go over the axel and its a pain in the *** to get them there.make sure you put the lines in the front first though or else its next to impossible to do it after.the fuel lines are the two inside lines that run along the underside of the car so jsut replace them. more commenly though, therer was a rupture along one of the fittings and ran down the line on the outside.good luck

Well here are some pics of the aftermath. I can't tell just yetwhich one is leaking because I need another person to crankwhile I'm down there looking. Sucks working alone. :(

no no no, don't drop the tank unless you absolutely have to. There's one hose on the right side deep in there hidden by the bottom of the trunk. I haven't seen damage and stuff on that hose but all the other rubber stuff is pretty easily changed
