While that's probably an easy option, the cars in question I'm talking about (4 I know of), all run the same setup and don't have a jet/syphon pump. They run twin in tank pumps with a custom top hat that has two fuel lines running all the way to the fuel rail. All have been tracked and all have gotten low tanks and zero issues with surging / running out of fuel. Does this Jet Pump really work as well as we think it does?
