effective product sealing fuel line weeping?

[dtbaker61]

...now that I have driven the car since replacing the slave cyl.... there is a significant amount of gas 'weeping' out around the fuel line pitting that goes into my glass fuel bowl.

I tried tightening, but that did not seem to do it... threads may have been damaged in the past, who knows.

Is there any effective product ya'll would recommend putting on the fitting threads that will help create a good seal, and stop the weeping?

LockTite. Nothing seems to soften it except relatively high heat.

Noting, of course, the inherent danger of high heat near leaky fuel line..
(Of course, liquid gasoline burns; it's the vapors that explode. And I didn't research the relevant temps required for that vs. releasing loctite...)

But you might have to undo it at a later date, and it would be best if that was a safe process.

Is that a compression fitting, or a hose barb that threads into a casting, or something else? If its a compression fitting, the threads really don't "keep the gas in by themselves -- its the ring around the tube, and the mating surfaces that contact it.

Let us know, and I'll look at the one I have, too...

The release temp of LockTite is quite high, but if 242 (the common blue stuff) is used, it can be removed with wrenches, no problem. But you will need wrenches. No pliers, please!

Jomar WOG works really great. You can find it sometimes at farm supply or heavy machinery places.

Mine turned out to be a little compression fitting... not sure if that is a kludge or stock, but probably had been OVERTIGHENED and crushed the tube a little and no longer getting good compression.

I took the easy way out for now, and put a little PTFE pipe dope in back of the fitting so that the compression mashed the dope in the back. This sealed it up fine and should hold until I either re-run the line or remove the whole engine at some point.
