This is a BWD (Pollack) FSV2A from O'Reilly attached by 1 bolt to a simple bracket I cut & bent, with a scrap of galvanized gutter attached as a heat shield. The gauge had to be rewired because the new valve uses a polarity-reversing circuit.
The colored zip-ties ID the fuel lines & wires:
Y is pressure
R is rear
Gn is front
Wh is gauge
