My truck has factory dual tanks, so that solved part of the issue. The other thing about my truck is the PO swapped in a complete TBI setup from an 87, and in doing so replaced every wiring harness throughout the truck with those from the 87.

The 87's, having the TBI, have electric fuel pumps that are in the tank. So all I had to do was replace the pumps with ones capable of supplying the GenIII psi needs.

So whether you have one tank or two, you will need to get sending units from an 87 pickup, and the ACDelco EP381 pump(s). The fuel pumps attach to the sending unit and drop into the tank.

You have two choices on the tanks..... the original tanks will work fine, but they lack the sump that the 87 tanks have. The fuel pump sits in the sump to keep it from losing fuel on hard stops and corners. Your original tank will work, but at or below 1/4 tank, you might find the engine dieing from hard stops or corners.
