OK, long story short, did everything, truck got fuel from tank and it ran.


Then 4-6 minutes into running, I'm on the phone ecstatic about it.....I see the joint between the original line and the new line leaking.

Man o man....(I have known for a while that...)The fuel bowl leaks after the truck has stopped running and cooled down(does NOT when running)....and even after that it still takes a day to completely drain.--I was hoping that'd be the only fuel leak to fix. DAMN.

So, it looks like it may be a flared type setup, what can I use to seal it? I have tightened it down to the max, it helped but didn't stop.

Is this a joint from old steel line to new? If so, perhaps a compression fitting could be used, or teflon tape, depending on how bad the leak is. If it's really bad, the flare may be screwed up, or the fitting threads may have been stripped, at which point you'll have to cut it off, put on a new fitting, re-flare the piece, and hope it doesn't shorten your line. OR, you'll have to replace it all.

Does the float bowl leak out the carb, or drain back into the line?

P.S.>>Steel lines should always be flared. If your old line (or your new line) is not flared, that is your problem.

Well, first of all, the fuel bowl seal leaks directly out of the carb from what I can tell. It's no big deal just need a new paper gasket.

The joint is old steel to copper line. I know it's nuts, but I haven't heard any negative feedback from some shops so I think it's ok.

...the thing is, is that this worked in the past. This truck ran like this 20 years ago, and never leaked. I'm assuming it wasn't done the day before my dad bought it so I think it probably ran like this for years before my dad bought it.
Why is it leaking now? I don't know.

I'm going to tear it apart tomorrow and see what I'm dealing with(got dark as I found it). I just thought I'd get some people input.

Thank you very much.
