Maybe it's only the CIS cars, I don't know the earlier models.
I see the 930 guys and the turbo conversion guys talking about adding a second fuel pump up front to augment the pump in the engine bay.
My thought was why?
A newer style, in-tank pump is more than adequate to feed any EFI / turbo combination and it seems to me, a much simpler & cleaner approach to fuel delivery.
I'm planning on doing this mod when I switch to the tbitz EFI.
Will also utilize a return style FPR to circulate excess fuel back to the tank. it's easier on the pump and keeps cooler fuel available to the motor.
Every HP enthusiast knows to change from pulling the fuel to pushing it, the factory pump literally sucks!
The engine bay will look much cleaner without the fuel pump & fuel reservoir there and even the filter can be relocated down lower, out of sight.
