This SU double-ended fuel pump is designed for Austin Healey late BN4 through to BJ8 models where increased fuel delivery is required. It uses mechanical contact breaker points and operates as a dual-polarity 12-volt pump suitable for both positive and negative earth systems.
This pump incorporates two pumping chambers within a single assembly to deliver a higher fuel volume than a standard single SU pump. It is typically used in applications requiring increased flow capacity.
The pump uses SU’s traditional contact breaker points system rather than electronic switching. This preserves the original operating method and allows for conventional servicing.
The pump is designed for both positive and negative earth vehicles, making it suitable for original or converted electrical systems without modification.
Commonly used where higher fuel delivery is required. Installation suitability should be confirmed against system requirements.
DUAL POLARITY
No. It uses mechanical contact breaker points in line with traditional SU pump design.
Yes. The dual polarity design allows use on both positive and negative earth systems.
Not always. A standard single SU pump is sufficient for many applications, but a double pump may be used where increased fuel supply is needed.
A double-ended pump provides increased fuel delivery compared to a single pump, which can be beneficial in higher demand applications.
