6 Volt Fuel Pump

[Mike K]

I agree with Richard F on this . The SU (Skinner Union ) pumps work OK if a little basic maintenance is performed . The SU brand , derives from two brothers ( Skinner ) who developed the SU carby , the factory and patents were purchased by a William Morris in the 1920's I think . Some pre war Morris cars used SU pumps , the design didn't change much . I think Morris / Cooper S mini's of the 1960's used em too ......
a smaller version .


Many people dont realise many of the SU pump problems are caused by a weak diaphram spring . Everybody heads for the points , but , over time the return spring weakens and the thing won't work . A quick fix is to pull the spring apart and re-tension it . A new spring is cheap too .

When I was a kid , the LUCAS factory was on the corner of Bay road and Nepean Highway , Cheltenham , just opposite where Southland is now . They must have made millions of those C39-C40 genes there , or were they imported and assembled there ? It was a huge complex . I believe the first Holdens, FX-FJ used Lucas before going over to Bosch .

Lucas had a habit of using poor connectors , often , wires were just left bare and a simple screw in locking system meant that poor conductivity was the norm . Connectors would oxidise and all you needed to do was clean em up .
