LS Fuel tank/ electric fuel pump ideas/ input needed - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm about to embark on my latest project, swapping an LS1 onto a 72 swb chassis, then installing a 70 cab and clip. I am trying line out the major issues, one of which being the fuel system. Instead of going the "cubic dollar" route, I am trying to keep it low buck. I have a fuel tank out of an 82 Suburban I parted years ago. It seem that it is similar in width to the Blazer tank I used in another 72, but deeper. My thoughts are using a sending unit out of an 87-91 (that was originally equipped with an electric fuel pump) and instead of the tbi pump, I would use a pump from a newer vehicle, perhaps the donor 02 Trans Am, or newer LS equipped pickup.

Thoughts?
