Fuel Pump Controller – GM (13565638)

Fuel Pump Controller 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 Pump Controller 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 Pump Controller is listed as part 13565638 (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 Where a number has been superseded, the current reference is the one that ships, so check any supersession note before ordering.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 GM dealer-sourced stock rather than an equivalent, so the number on the Fuel Pump Controller traces straight back to the manufacturer.
