Hi David

Both front and rear pumps are currently out of stock as we still seek pattern pumps which last as well as OEM and which don't leak!

The change in front pump sound may in fact be due to intank pump failure.


To be sure intank has failed find a very quiet area to do the following DIY test:

Disconnect the front pump (release small tab with small screw driver and pull the 2 wire black plug off) Turn ignition on and listen at rear for intank high pitched whirring noise (very faint) This can be heard either by listening with filler cap off, or by listening underneath RH of car by fuel tank.


If nothing heard this proves Intank pump is duff or possibly a fractured pipe within the tank.
(Power to both pumps is applied for 50 seconds if engine isn't started , via Relay behind glove box)

Another symptom of intank failure is car will suffer fuel starvation when guage approaches 1/4 mark.
