Not on my Backdraft, i'm using an external swirlpot and Bosch EFI pump.
However, on my GT40 I did build it with an in-tank EFI pump, and its working fantastic. I should actually go back to my cobra and convert it.

I'm using the Aeromotive Phantom package, an EFI pump with a baffle foam insert, such that you don't need a swirl pot. I'm positive this will also fit in the plastic Backdraft tank.
