Leaky Edelbrock Fuel Pump
im not a big fan of teflon tape near the fuel system
it can get into the lines and clog stuff up
for my money, i use permatax aviation #3
its the franks red hot of sealants
Permatex 80019 Aviation Form-A-Gasket No. 3 Sealant, 4 oz. | eBay
of course, you can seal the fittings all you want, if it is leaking from the diaphragm, that wont do you any good
so what have you done to inspect that?
