Another small, easily over-looked part is the oil-pressure sending unit. We washed our old one and threaded it into the new engine. The chrome fuel-pump block-off plate is stock on the X302; a fuel-pump eccentric is too, so carbureted applications require simply bolting on the engine-driven fuel pump. The FRPP oil filter is included with the engine; a water pump is not. We ordered FRPP's M-8501-C50 reverse-rotation aluminum pump, which fits all '86-'93 Mustangs.
