Fuel Fitting At Rail - Possible Leak?

[cprince]

I was changing my alternator yesterday when I noticed that my ratchet handle smacked something on a few back swings... then I realized that I could smell gas.

Long story short, there is a fitting at the injector rail... looks like a pop-snap-twisty type fitting... it was leaking pretty good. I fiddled around with it and I *think* it stopped... but...

I checked it a few times yesterday, and it seemed dry, but today I thought I smelled gas. Hard to say if I am being paranoid or not...

Are these fittings a pain in the ass to change and/or susceptible to breaking?



Thanks!

They are a huge PITA if you don't have the right tools. I've gone so far as to replace the entire nylon line with fuel injection rated hose and never had an issue with leakage afterwards.

The plastic elbow ones on the L36 don't need any tools to release them. The metal straight ones on the L67 do need the special fuel line release tool.

Dorman sells replacement fittings that come with like 24" of hose that you connect to your original line. If yours is leaking, you should be able to fix it for around $20.

Yep, I had one bust off on my Lesabre while I was riding down the road, car fully warmed, and it dumped about a 1/4 tank on my LIM. I'm lucky it didn't catch on fire. I had to get mine done at a shop, due to the fact that you really have to boil the lines to get the patch kit in, but the dorman repair kit that comes with lines and a barb fixed mine. Just be sure to get the right size kit to fit the line, the send line and return line are two different sizes, 5/8 and 3/4 I think, but I'm not positive. I personally would replace it just to be safe if it popped off with a simple ratchet smack.

Yeah, the seal went bad on my 98 SSE once, it would actively leak every time you touched it. I drove 200 miles all the way to Don's house to have it fixed!

Luckily, he had that awesome dorman kit with the tool and the ends to actually GET the new barbed fitting in there instead of trying to perform the miracle by hand.

[Jfridge92]

Agreed, trying to do that in a gas station parking lot resulted in me getting it towed to a shop to use supplies. If you do it at home, dipping the lines in boiling water can make it easier to get the barb in, but this tool sounds MUCH better.

Where can I get this tool? What does it look like?

Thanks Haro

So I got the Dorman repair kit and even after boiling the lines try didn't want to go all the way over the barbs. I'm going to try heating them up with blow dryer but I'm ready to give up on it. Any suggestions on a steel line to fit an SSEI sending line? If not a full nylon line?

[harofreak00]

They are really hard to get all the way on. I use a heat gun. If you can get it at least 3 barbs on you should be fine, its only 50psi, not 3000.

[phamnett]

I tried with an extra hot blow dryer and boiling water to put the barbs over. I think I tore the end of the nylon hose trying to pull it over with my forceps. What would you recommend if I can't get it over?

[harofreak00]

Try harder is the only advice I have.

Phamnett which Dorman repair kit do you have?

[phamnett]

DORMAN Part # 800058 3/8 In. Quick Connector, Straight w/ 18 In. of 3/8 In. Nylon Tube and a Union

[ron350]

OK no wonder you can’t install that connector.
Part #800058 is just the replacement part you need Dorman install tool.

You need Dorman repair kit #800-300 to install the fuel line connector. That tool kit has an adaptor to hold the fuel line and an adaptor to hold the end connector while you pump the handle to force the connector in to the fuel line.

[MattStrike]

Or use the dorman push to connect fitting... No boiling lines or special tools.

I didn't get the dorman kit. The gm line said non-repairable. So the whole line had to be replaced. I couldn't even get the barb in with a torch on it. GM discontinued the original part so 2 screw clamps and a flexible hose are on there now and it works.
