Gonna have to replace the gasket, IF it is leaking from the fitting going into the carb. Once tightened so far, the gasket will split. AS Dennis mentioned, the fuel line itself can develop a split, or the flare can be crushed enough to leak.
One trick to a temporary "fix" for the gasket is to run a couple rounds of sewing thread around behind it. You want to put the thread between the gasket, and the fitting, where it seats. This will make the gasket "thicker", basically, so it will seal. IF the gasket is actually split tho, this won't do any good, and will prolly make it worse.
My suggestion would be to remove the fitting, and replace the gasket. I don't know that you can get that gasket by itself...it does come in a carb O/H kit, tho...

Hey Fellers,

Thanks for the input on this.

I checked Auto Zone for just such a gasket with no success. The guy behind the counter might have been wingin' it. He told me the Edelbrock rebuild kit would have the gasket I need. I just was'nt sure he was right, so I held off. Maybe just a bad vibe, I dunno.

There are a few other local places I'll try for just the gasket. And I'll hope the fuel line is ok until I take it apart.

Get some gasket material and cut your own using the old one as a guide.

Won't work, Dave....
This is a very thin, nylon gasket/seal. It fits around a small lip on the fuel inlet fitting, as you can see from the pic I posted above.
Kev, I may have a few of them in my carb box, if you can't locate one locally. I would suggest asking your local mechanic, or a carb shop, if you have one in your area. If you can't find one, send me a P/M with yer address, and I'll throw one in the mail for ya, providing I can find them.

Kevin, Go to a parts place that has one of those "Help" parts isles. They have a package of various carb gaskets. Bring the fitting with you and see if you can match it up. Sometimes those packages "accidentally" open so I can make sure it's the right one. Wink  I does buy the package iffin it matches tho...

So YOU'RE the one that does that?!?!?Angry


I have a Pep-Gurls right next to the shop here, and about half of the "Help" packages have usually been opened over there. Sometimes, they gots tape holding it back together, and sometimes staples, but most of the time, you pull the package off the hanger, and the crap just falls out on da floor!
I never thought about looking there, tho...good call there Paul!

I did have some input on the brown stain..make sure that you tighten the fuel filter first then the fuel line..it may tweak the fuel line then vibrate the filter loose..I looked for one of those gaskets but didn't find any..I use them whenever I rebuild the carb I am working on..I did just see commercial for pep nuts and they are having dollar days..maybe that open box in the help section will be worth it being half the stuff is missing..

A local carb. shop had them. The guy there is not a big fan of the Q-Jet but for this he was right on the money. That was a whole bunch easier than I thought it would be.

Joel, thanks anyhow for offerin' to send one my way.

Another slam dunk by the fine folks here at C3VR!  Thumbs Up Thumbs Up
