New Engine - Weird Leak
New Engine - Weird Leak Just fired up my 383 for the first time. Runs great but I have the weirdest leak. I have a fuel leak that has me baffled. I hot wired the fuel pump to prime the system and set the FP Regulator to the correct setting. Pump ran for several minutes....no leaks.
Start the engine idle smooths out and all seems good until I notice the puddle of fuel under the car. Go underneath and fuel is dripping down of the starter and trans bell housing. Shut the car off fire up the fuel pump.....no leak....Start the engine let run for a few minutes......fuel leak. For the life of me I can't seem to find where its coming from and why only when the engine is running. I checked the fuel rail and intake and nothing appears to be wet.
Basic terms:
Fuel pump on + engine off = no leak
Engine on = leak
Am I the only one who had experienced this and if not can someone offer some assistance.

why did you put an aftermarket regulator on it? Why an adjustable one?
My bet is you spent a lot of money on a part you shouldn't have even been considering and then bought junk(maybe with a big name) that is leaking when exposed to manifold vacuum.
For the VAST majority of LT1 builds even high effort builds the stock regulator is the right choice.
