I have a 68 SS 396 with the stock Q-jet.(all original stuff) I found a leak in the front of the carb.(fuel filter area) It looks like a round factory plug or pressed in fitting. I tried a couple ideas. The best was JB Weld. Worked for a couple weeks, but started leaking again.

Any help to fix this and save my carb would be appreciated. Thanks.

Have you tried, using the flat part of a small hammer, tap around the inside part of the outer circle several times, (NOT the plug itself) just outer circle, don't hit real hard, but hard enough to try and make it seal back by itself ..... This trick has been done before, and worked sucessfully. Good luck. I believe epoxy is used by some carb re-builders, but I suspect the carb may have to be taken apart to use the epoxy sucessfully.

Thanks. I have not tried that yet. I will have to try it in the next couple days, but it is pretty cold up here in northern MN.

It still has the JB weld on it. I wonder if i should try to remove it first or just try it like it is??

I'd buff the JB off before reseating the lead ring with a small hammer. Don't hit the plug at all.

If the reseating doesn't work, use a dremel or similar tool with grinder bit to clean and scuff the ring, plug, and surrounding area. Make sure all the JB Weld is removed. Go to a boat dealer and get some "Marine-Tex' epoxy and seal it with that. Cover the entire plug and ring out to about 1/8" outside the ring. Make the epoxy at least 1/16" thick. This is all after you drain the gas down below the plug by disconnecting the fuel line.

Howdy all. Thanks for your help on this issue. Sorry it took so long to respond. Tapping on the carb with a hammer trick did work. I did buy some marine tex, but did not apply it since the leak has stopped. Will keep it just in case. Thanks again.
