tanks inc pa4 vs surge tank for efi

It won't fit on top of the tank because of the trunk floor unless you weld in a recessed area for it. I run a surge tank in my '68 feed by a stock tank with 3/8 feed and return lines feed by a pusher pump right outside the tank. It works great and love it. I'm considering swapping my '70 over to EFI, and will likely use an in-tank pump/pumps and a surge tank.

I won't be cutting the trunk floor, so I will have to recess my tank too. Right now, it's got a custom 30 gallon stainless tank with a -12 feed to a traditional dual return fuel system.

A lot of the very high output tuner guys add surge tanks to their factory EFI cars due to fuel slosh issues even with well designed factory tanks.
