Gas leak, need help

My 94 LeSabre leaks gas at the plastic connector from the fuel line to the fuel rail. GM does not carry parts this old, and NAPA said they carry nothing for the fuel rail. Need some help locating or replacing these. Saw a similar question from 1997 but never an answer. Thanks

Welcome to AF, I believe Motor Mite help parts makes a line repair kit which Napa should know about.

Thanks for the tip, I will give them a try. I went to Advanced Auto parts, and they had some connectors, but none looked right.
I also went to the Junk Yard and found what looked to be an identical connector on a 98 Le Sabre, but had no idea how to get it off, short of sawing the gas rail pipe.
Do you have any idea how these get replaced?

All you need is a tool like the one shown below, you can get one at Advanced Auto for less than 10-bucks. Be sure the one you buy is for GM cars.

Hello:

First, some assumptions:
1) Your bad connection is the 3/8 inch supply line to the rail (the return line coming off the regulator is 5/16 on this car).
2) Your leak is at the quick connect connector.

I believe what you need is this:
Dorman part #800-059
3/8" Quick Connector, 90 degree w/ 18" of 3/8" Nylon Tube and a Union.

I've seen this at both AutoZone and Advance Auto parts. Check it out at the Dorman site if you want.

You'll need to cut your line and splice this in and you'll have a new quick connector that doesn't leak. The instructions w/ this item say to soak the nylon fuel lines in hot water for 10 minutes, then press them into a union which comes w/ the kit. A bit of motor oil on the union should ease the pressing in process. There is a tool for this, but I think it can be done carefully w/ pliers and a clamp.

On my 94, I don't need a tool to release the quick connector, just squeeze the tabs together and pull it off. You may want to add a Dorman part #800-306 Fuel Line Pinch Clamp Assortment (comes w/ 3/8 and 5/16 clamps to crimp over the fuel tube that you pressed on the brass union).

I'm researching fuel line stuff trying to solve a problem of my own related to the fuel filter, so I'm pretty up to date on all the Dorman repair stuff.

Good Luck,
TC

Thanks for the help. I went back to NAPA yesterday and located a NAPA part that sounds just like what you recommended. There is a small round piece in the bag which the Service dept man said was a removal tool. Is this something I can do myself or should I resort to my local mechanic? I am reasonably handy, but don't want to get stuck and have to tow it to the shop.

I used one of the spliced in replacement lines on my '97 when it was leaking at the fuel rail. I ordered the kit on-line. Had to cut the plastic line and insert the union. It required clamps on each end; old to new line. The rest was easy. It clipped on to the rail and it was done. I used some oil on the hard plastic line to slip the lines over the union.

I had a similar problem from the fuel tank to the fuel filter, but used a peice of high pressure fuel line to fix that part. Those quick connects tend to leak.

A-OK . Installed a NAPA Quick Disconnect Fuel Line Repair Kit in minutes, once I decided to go that route. I used hot water on the new piece, and oil on the old piece when attaching to the connector. The plastic lines crimp or bend easily, hopefully they won't leak where they bent. I first tried to replace the o-rings in the old disconnect. That was a disaster, I don't recommend that.
