SU FUEL PUMP 12V DUAL POLARITY HIGH PRESSURE HIGH FLOW

Single ended, high pressure points type Pump. Minimum flow 15 gallons per hour. 2 Pints Per Minute (US measurement).

The threaded fuel pipe connections are not supplied with the pump

The AUF300 series is superseded by the AZX1300 series pumps [AZX1307 & AZX1308, see below] 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.

Dual Polarity. High pressure 12 Volt with minimum flow of 15 gallons per hour.

Between 3 & 3.8 PSI. Points Type, Dual Polarity (can be used with Negative OR Positive Earth)  These pumps mount at the rear of the vehicle

Supersedes these SU pumps: AUA173; AUF301; AUF302; AUF303; AUF305; AUF325; AZX1304; AZX1306; AZX1309; AZX1318; AZX1320

The AZX1308 can be used in place of the early LCS type pumps as well.

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