Product Description
For the front/midship/side OEM plastic diesel tank on the 1985-1986 F-Series — one of a sequence of near-identical diesel sending units MTS lists by year range, so match yours carefully against FMSU-12DEPS, FMSU-4DES, FMSU-5DES, FMSU-6DES, and FMSU-7DES.
Fuel gauges don't usually fail gradually — they're fine, then suddenly wrong, and a bad sending unit is almost always the reason. This one matches the OEM ohm range and mounting pattern so the gauge reads correctly from the first mile, not just close enough to guess by.
