What kind of fuel pump does a Jaguar XKE have?
The Jaguar XKE / E-type has an electronic SU fuel pump typical of many British cars of the 1950’s-70’s. These pumps are simple devices that work on a set of points that activate an electromagnetic field and cause a rubber diaphragm to move and pump the fuel.
Why are the rubber diaphragms on my Jaguar XKE being replaced?
The ethanol content in modern fuels is thought to be destructive to the older rubber diaphragms. New ethanol-resistant diaphragms are available as are solid state SU pumps that recreate the look and function of the originals, but without mechanical points.
How to restore a Jaguar XKE E Type?
Once the banjo connections and electrical wires have been removed you can unbolt the pump mount and withdraw the pump and mount. On my pump you could see the gasket that was leaking. The next stage is to remove the pump from its mount, place the new pump into the mount and reinstall. There are aluminum crush-washers on the banjo connections.
Can a SU fuel pump be replaced on an XKE?
The good thing is that on Series II E-types replacing the SU fuel pump is very straight forward and the pump itself is readily available and not too expensive. You can rebuild the old points type pumps with new points, diaphragm and gaskets – but in terms of time versus cost it might be easier to buy a new unit.
