I'm converting a carbureted car to EFI, using a stock reproduction tank (no baffling). I wanted to modify a fuel pump module from an EFI car, but I think my tank is just too shallow for that to work (~6" depth). I plan to fabricate some kind of bucket for the pump and dump the return line into it to help prevent starvation, and i'm wondering how much capacity I really need in my bucket. Would something like this be enough?
This is not going to be a race car, and I'll rarely drive it in anger. Maybe an occasional autocross. So how much slosh protection do I really need?
So what happens when the fuel is below the bucket height? It seems like it would suck it dry super quick and then what? Whatever happens to splash in? You probably need some holes for passive filling from the rest of the tank.
In reply to theruleslawyer :
agreed, i'll have holes in mine. I suspect there are holes in the bottom of that one under the fuel filter to draw in from the bottom.
I imagine the idea of the bucket is to have only enough fuel to supply the engine until the "slosh" equalizes back out?
It looks like there's at least one hole in that bucket - on the end.
I'm not sure dumping the return line into the bucket is a good idea as it will cause turbulence and might cause cavitation of the pump?
In reply to MiniDave :
that's how the factory bucket i purchased does it, and to my knowledge is standard practice...hopefully works well?
