SU Fuel Pump 12V High Pressure Positive Earth

Single ended Electronic type Pump. Positive earth. High pressure 12 Volt with minimum flow of 15 gallons per hour. boot mounted.

The threaded fuel pipe connections are not supplied with the pump

The AUF 300 series is superseded by the AZX 1300 series pumps [see below] 

These are a high capacity adaptation of the AUF 200/1200, the pump body having been redesigned to incorporate a flow-smoothing unit and an air bottle.

The flow-smoothing unit consists of a diaphragm and housing situated above the delivery chamber and outlet passage.

Fuel pressure pulsations are damped by the air contained in the housing, resulting in a reduction of flow pressure variations and an increase in output for a given rate of operation.

A large compartment formed in the inlet side of the pump acts as an air cushion and smoothes the pressure pulsations of the incoming fuel; it also prevents high negative pressure being created in the pump body.

These pumps mount at the rear of the vehicle

An earthing terminal is provided on all pumps and it is essential this connection is fully effective
