Leaking fuel line
Hi all,
92 RS 3.1 MPFI
I have a leak in my fuel line. It is coming out of the bottom of the cylinder (see attached picture) in the fuel line located under the throttle body. It's a pretty consistent drip.
Can anyone tell me what that cylinder is? Has anyone else had a leak there? It looks like (if no one has an easier fix) I'd have to replace that whole section of the fuel line. It's all one metal piece that starts to the right of the air conditioning compressor, goes under the throttle body, and then leads under the intake manifold to the back side of the engine near the firewall.
Thank you for your input.

Re: Leaking fuel line
Best guess is it's probably a pulse dampener. Never seen one leak. I'd make sure it's actually leaking from there, and not leaking somewhere else and just running and dripping there.
I've got the entire fuel line assembly off a 3.1 laying in the garage. If you decide to replace it, send me a PM.

Re: Leaking fuel line
And I think you're right, Drew. Upon further inspection, I'm pretty sure the leak is coming from the fuel line going into the right side of the metal cylinder. I might try some JB weld.

* JB weld is great stuff , but since we are talking fuel leak I think I'd pass on using it here .....

Re: Leaking fuel line
Thanks for the reply OrangeBird.
Well, JB weld didn't work anyway (still a slow, steady leak). I went to a salvage yard and found a 2.8 L Camaro and took the fuel line from it. (And you're right, didn't have that cylinder piece.)
I'll install it today. I'm sure it'll be fine. I'm still very curious, though. What is that?

I am only suspicious because I've seen a bunch of these 60 degree V6 engines and I can't ever recall seeing that part . If the 89 plumbing you got fits , works , and don't leak , by all means run it and I'll bet it runs just as good with or without it , there is nothing presently dampening my fuel pulses and my lil V6 runs great

Re: Leaking fuel line
Both of my 3.1L 91's have had the can. It's hard to guess exactly what GM was trying to accomplish, but I wouldn't worry about it too much. A lot of head scratchers like this are intended to resolve a subtle noise, or imperceptible issue. 25 years later it probably doesn't matter as much as the ability to run and drive without bursting into flames.
