Fuel Injection Pump – GM (55585049)

Fuel Injection Pump pressurises fuel for the injection system. It is cooled and lubricated by the fuel it moves, which is why running a tank low shortens its life.

Replace the Fuel Injection Pump when pressure is below specification with good voltage at the connector, when the pump is noisy and hot, or when it fails to prime. Check the relay and the ground before condemning it.

This Fuel Injection Pump is listed as part 55585049 (Fuel Pumps & Senders). Where a number has been superseded, the current reference is the one that ships, so check any supersession note before ordering.

This is genuine GM stock, supplied for the Fuel Injection Pump with the manufacturer number intact so the reference on the box matches the catalogue.
