Fuel line leak

Ok, I am stumped. I had a carb for my 69 Z28 (302) rebuilt and installed it on my 68 Z28 (302) while the 68 carb was out getting rebuilt (same person) the 68 had not run for 30 years, got it running just fine. Received the 68 carb back and swapped them out to have the correct date coded carb on the correct car. And now the carb on the 68 leaks at both lines into the carb at the carb.

I have looked at the flares and the seats and see nothing!

Any thoughts?

Re: Fuel line leak

Visit your local hydraulic & pneumatic hose shop and get a couple copper crush washers for the flares.
Snug the fittings and problem gone.

Re: Fuel line leak

Another trick you might try before you go,
Apply a drop of oil on the back side of the tubing flare, then slide up the nut and tighten.
Oil can be from engine dipstick.

Re: Fuel line leak

The fuel inlet nuts thread into the carb float bowls. The fuel line flare fittings thread into the fuel inlet nuts. There should be a steel gasket between each fuel inlet nut and the float bowl. If they are missing that is the cause of your leaks. http://www.summitracing.com/parts/hly-108-8

Re: Fuel line leak

Thanks for the reply's. The washers mentioned are not missing so that was not the issue.

I live in a foothill community and trying to find copper crush washers is impossible but after a little memory loss return I realized that the copper crush was the same item I use in my industry (refrigeration) and we call them flare bonnets. Dug around the shop and found a box of them. Put them in and no more leaks.

Thanks for jogging my memory Everett#2390.

This allowed me to get my Corvette Bronze 68 Z/28 RS running and drive it around a little. it had not run for 30 years.

Thanks again
