I have a problem maybe someone could help me out with. When I bought my 79 C-20 with the 350 I was going change out the fuel filter inside the carb. I noticed that someone had stripped the female threads inside the body a little bit and wrapped them with teflon tape to make it bite. I replaced the filter and wrapped the male threads with Teflon like my predecessor had done and it held OK for about 14,000 miles. Today I was checking my trans fluid and noticed it drip . I tried to snug it up a little bit but it got worse. I tried more teflon and that did not help. I'm afraid I set my truck on fire with it like it is. Is there a way to repair this or do I have another carb in my future?

Teflon and gas don't mix the gas should break it down over time. i would find some permatex at a parts store for making a seal that has constant contact with gas and see how that works. (http://ace.imageg.net/graphics/product_images/pACE-984936reg.jpg) coper seems to be the one for you

They make a self tapping oversize fuel filter housing to repair that. Here is one of many options for those: http://www.gesslerheadporting.com/members/gesslerheadporting/ghp.nsf/822dcaaaa26c6da985256dd80023623d/a661ef84a4b8f9f6852574fd005f54f8!OpenDocument (http://www.gesslerheadporting.com/members/gesslerheadporting/ghp.nsf/822dcaaaa26c6da985256dd80023623d/a661ef84a4b8f9f6852574fd005f54f8!OpenDocument)
That would be my first choice for repair. Second, sort of hack approach would be to use gas tank sealer, jb weld, etc. to seal your filter housing permanently to the carb. and use an in-line filter instead.

I agree, try a new fitting or remove the stock filter and carefully epoxy it in and use an inline filter.

That's cool I never knew about them

Thanks for all the help guys. I am ordering the self tapping fuel filter fitting recommended by Jaredts. I am trying to find one locally but not having much luck. I have a 78 parts truck in the back and I did try the fitting off of it. Same results. Leaked. Speaking of hacks, I tried the JB Weld on the threads but it leaked too. I had to laugh when I read that since I'd already done it! ;D
I rewrapped the fitting with teflon tape over the JB Weld and it screwed it back in. Stopped leaking for now. I think it will hold good enough until my part comes in. I'll let yall know how it works.

With mine I JB Welded it back in. The threads were shot. Well I used a AN type fitting cause Im running braided lines. But the JB Weld is holding up great. Im using an inline filter. Much easier than the possibility of ruining a good carb.

Hey Guys, I found a self tapping fuel inlet at O'Reillys for $11.00 in their "HELP section". It's part number 55140, it's 1 inch. I think some used 7/8". Worked like a charm. I didn't even know they existed. Thanks Jaredts for letting me know they made something like that. I will post a pick when I figure out how to do it. ;D

No problem--good to know they are available at a local parts store (not that I ever plan on needing one!)
