The PO left me w/ one so rusted that . . . .
I took a fine mesh-screen and soldered it to fit inside a brass pipe (that threads into the bottom of my tank) the screen was 2.0'' long, so the screen acts as a pre-filter. This way it would not allow any crud into the fuel line. Add a filter and that worked.
Not only that he (po) poured a tank sealer into the tank w/o completely cleaning /degreasing. The sealer didn't really coat and a sheet of coating blocked 60% of the gas spout filler tube inlet. Gas always flushed out when we tried to fill the tank. We didn't see that until I took the rubber hose and filler tube off.
We have now replaced the cab mount tank w/ an under bed one.
