On my 1969 Firebird, I've always had issues with the fuel returning to the tank quickly and leaving me in a situation of not being able to get the car started again after short periods of non-use. After this happens, by the time cranking has produced fuel to the carb, the high compression 455 has eaten up all the juice in the battery and there's nothing left to fire the motor.
Is this fairly normal to see all the fuel exit the system within a couple days? To the point that the only way I can realistically get the car to start is to squirt some fuel in the carb enough to fire the motor temporarily and get fuel up to the carb. That's fine right now with the car still being worked on. Once finished though I don't want to have to do that every time I want to take it out on a weekend.
The engine is a Pontiac 455 with an early performer intake (P4B) and a 700cfm Edelbrock performer that is out of the box. I'll be replacing that with a carter 9800S that I have and will be rebuilding. But for now I just need to figure out this leak back issue.
This car did have AC on it from the factory, so it has the 3/8" feed lines and a 1/4" return line.
Any insight would be greatly appreciated. Thanks!
