There are a few interesting suggestions here, but I'm going to stay with the QFT for now. For what it is worth, this is a '69 F100 with the fuel tank behind the seat in the cab. A submerged pump in the tank is NOT an option. I may consider moving the tank to the rear under the bed and behind the axle in the future, but it is a significant project that involves moving a frame cross member (and removing the bed and box), so not in my near term plans.
I'll spend my next free $$ on an Eaton Trutrac for the 9".
