Mack 70GC310, 70GC248P2 Fuel Pump Lever Assembly

Mack 70GC310 and 70GC248P2 Fuel Pump Lever Assembly is a replacement lever for Mack engines that use a mechanical fuel pump system. The lever mates with the pump cam to actuate the fuel pump plunger, translating crankshaft rotation into a precisely timed fuel delivery cycle that supports reliable combustion, steady idle, and consistent torque. Identify fitment by confirming part numbers 70GC310 and 70GC248P2 to ensure correct alignment and mounting for applicable Mack models and to avoid improper pump actuation that could affect fuel pressure. A properly installed lever maintains steady fuel pressurization and reliable pump operation, contributing to easier starting and smoother engine operation under load, even in demanding conditions. For proper timing and actuation within a mechanical fuel system, use this Mack lever assembly with the corresponding pump components and verify compatibility with your engine service guide, maintenance manual, or the manufacturer’s specifications.
