What is this

Is this some kind of factory electric fuel pump? I've never seen it on any of the trucks and it looks original? It's right under the driver seat on the Scab cab I just got. I'll get it out tomorrow and take a closer look/pic.

Looks like the remnants of an old tank switching solenoid.

Just two hoses. My other truck has the tank selector bolted to the frame.

If genuine Ford:

D5TZ-9189-B (replaced D8TZ-9189-A & D5TZ-9189-A) .. Fuel Tank Selector Valve & Solenoid Assy / Marked: D5TB-9F271-AA or D8TB-9F271-AA or D9TB-9F271-AA

1975/79 F100/350 with mid-ship & aft axle fuel tanks.

D5TZ-9A050-A .. Selector Switch-located in heater panel / 1975/79 F100/350: Switches the tanks and the dash fuel gauge.
-------------------------------------------------------------------------------------------------------------------------------------------
1973/74's with dual tanks had a manually operated fuel tank selector lever located on floor by drivers side of the seat.

Selector switch located in heater panel only switched the dash fuel gauge from one tank to the other.

My 75 f250 CS and parts 76 f150 4x4 have this electric fuel switch under the drivers floor board. My 79 f150 4x4 has it in front of the rear tank.

Weird. This cabs door sticker says man date is 4/77 so maybe it was still early enough

I have the manual valve and the elec valve. There are pieces of hose on both so at some time they were in use. I do have power at the elec valve when I switch the switch on the dash. Gonna replace it with a generic valve after I clean out the mid ship tank.
