IMPORTANT:
Manual fuel priming pump (hand primer) for Cat 3064/3066 engines. IDENTICAL to Mitsubishi 105220-7180 (S4K/S6K) — same weight, same specs, same price. Cat 3064 = Mitsubishi S4K (4.3L 4-cyl); Cat 3066 = Mitsubishi S6K (6.4L 6-cyl). These are Mitsubishi engines sold under the Caterpillar brand.
For excavators (311C/312C/312C L, 1990-2026 production range). Used to bleed air from fuel system after filter changes or service. Pump by hand until fuel flows freely from bleed screw with no air bubbles. If priming feels weak or spongy, the internal diaphragm may be deteriorated.
⚠️ Cat 255-2969 and Mitsubishi 105220-7180 are identical pumps.
