where do you put it? Upstream or downstream from the existing fuel pump? It works with fuel injected set ups, yah?
A fuel accumulator is a small tank (1 quart or more) fed by a low pressure pump drawing from the tank, with a return line that goes back to the tank.
The return fitting is at the top of the tank so it stays filled at all times.
The primary fuel injection system draws fuel from the bottom of the accumulator and returns the excess back to the accumulator.
That way the high pressure FI system
never sucks air unless the fuel tank is totally empty.
It is well worth the investment if you're chasing trophies.
