I'm not talking about swapping hats i'm just contemplating switching fuel pumps in the same hat with a large hose clamp to keep it in place. The reason i ask is i got my hands on 1 focus pump and a 03 cobra pump. At 40 psi they flow nearly twice as much as a stock pump does. I think they will work because a fuel pump is a fuel pump. If Dave would ever answer his phone i would ask him.
