Six Pack Carb Fuel Leak
I have a set of new Holley six pack carbs with the promax metering plates installed in the outboards. Ran the carbs about a year ago with a mechanical fuel pump everything was fine except the 2 middle cylinders on both sides read 300 degrees hotter than the outer cylinders. No matter what adjustments I made the temperature difference stayed the same. Long story short I bought a Fitech tri-power unit and converted to efi with an intake fuel pump. Never could get it to run right so I decided to go back to the carbs. Installed a regulator at 7 psi running to the carbs. The outboard carbs are leaking somewhere towards the bottom but I cant tell where. I've changed the gasket behind the metering plate thinking it was leaking there but that didn't help. Even when fuel is shut off it continues to leak until the float bowl is empty. I opened the sight plug on one and sprayed carb cleaner in it while it was off car and it all leaked out, it runs everywhere so you cant tell where its coming from. Anybody have any thoughts about where it could be leaking from? Nothing has changed except an electric fuel pump from when they ran and didn't leak a year ago.
