I have a supercharged 2001 Bullitt that makes 400 to the wheels. The car was having hesitation issues between shifts, and I read that removing a check valve (PPRV delete) on the fuel pump eliminated the issue. After removing the valve, it has hot starting issues. I’m looking at going with a return system with dual pumps in a hat that goes in the stock tank. When would I need to upgrade to a Cobra style tank with baffling? It seems to me that the new hat doesn’t have any baffling. Has anyone had an issue of the pumps sucking air? And should I use a Hobbs switch on one pump so it comes on with boost?
