The gas lines that connect the fuel pump on the passenger side to the fuel pump on the driver side run between the tank and the floor. Has anyone replaced these lines. The come as a pair and have connectors on each end. Do you lower the tank or can they be slid between the floor and tank? Any ideas? The hose part number is XR87950.

 

Hi David,

I can't answer your question about whether the lines can be replaced without dropping the tank. However, you may find my recent thread of interest as far as those miserable locking couplings at each end:

And this one, where I learned how those couplings work:

During my moaning and wailing stage of research, I came across this fuel tank on eBay with a fairly clear view of the lines:

If you could get in there, you might be able to free the lines from the clips without dropping the tank.

 

I've seen that photo. The wiring harness is the issue. It is clipped on both sides too far inside the body to reach it or put it back on without special tools or tricks. There might be someone who has done this job. This disaster of a fuel pump has been worked on before me and they must have used pliers or something to get the high pressure fitting out. All scared up and now way to splice it. Let's hope it doesn't leak when I put it back in the new pump. That fuel pump I took out of this thing is really a mess. A filter and gas line inside the tank? Ridiculous. New fuel pump will NOT have that mess. There is a another YouTube video where the mechanic seemed surprised about all the filters.

 

Have you peeled back the insulation all the way under the middle of the seat? A few inches inboard of the pump opening, towards the front, I noticed a small oval rubber plug. It's maybe 1.5" x 3". I wonder if there are more plugs like that near the center of the vehicle. If so, you might be able to get in there for access to the clips. See the picture below, at the upper right corner.

Always blame a previous owner. Well played!


Did you see how I spliced mine, with details in the previous link? I didn't think I'd be able to do it, but it wasn't too difficult after all.

 

I have one small inspection plug on each side. Not enough to remove the lines. The hook is that wiring harness clipped to the gas hose and I can't get to the two clips in the middle. Where did you get your new fittings? They look very good. I did repair the damaged white (small) fitting where Sir Jackleg from a Jag dealer "fixed" this. I wonder if it was recalled. That pump with a fuel filter inside the tank was nuts.

 

Yeah, that's pretty frustrating. Have you investigated how difficult it would be to drop the tank? I assumed (Danger! Danger!) it would be a lot of work, but perhaps it isn't so bad. The tank may not need to come all the way down, maybe just a few inches to snake your hand up there.

I fabricated them from brass 1/8" NPT fittings from my local hardware store. They came from bins of loose parts, so it's not like I can say order part #123 from company ABC. For the part that plugs into the coupling on the pump module, I turned down a short length of brass pipe on my metal lathe. Not sure what your capabilities are, but that might get spendy if you had to hire a machine shop do the fabrication.

 

Drop the tank....$950. NO. The high pressure side (white) fitting is the issue. When Sir Jackleg pliered the fitting out, the damage was too much. It has a pinhole in it and with high pressure, it will not work. Taking it out the second time just made the hole larger. I tried to patch it but the pressure went right through the patch. I cut the white fitting off and will find it somewhere. I have just enough space to put in a new fitting it the plastic hose doesn't spit. More later.

 

buy used couplings off ebay they’re sold as lincoln ls.

then you get a nylon hose union and heat gun

 

A heat gun on a gas line? I'm not sure that would be in my talent box. I like the used part idea.

 

Gas line fitting problem SOLVED. The gas is flowing and the leaks are no more. Choices were: 1. Lower tank 2. work between the body and tank. Lowering a tank full of fuel was a NO. Working between the tank and body was what I did. I couldn't get the high and low pressure lines out by sliding them. The ground wire and electrical harness that is clipped to the gas line were too hard to reach. The fitting is virtually unavailable so I bought this used assembly and cut a fitting off the end and installed a gates flexible gas hose right behind the installed lines. I then disabled the high side line for good (cut off both ends). I reattached both high sided fittings and the job was done. The high side fitting is the white one. The black fitting is the low side. I'll keep the used part I bought just in case I have to replace another fitting in 20 years.
