Top Cover of fuel pump
The shapped O-Ring is the offender in this problem.. It hardens up and doesn’t seal against the pump body any more..
So can be fixed in the car by removing the 4 top (Hex or Allan Key) bolts.
|The two seals
on the top cover..
Both should be replaced..
I got both for $5 from Precision Diesel in O’Connor in Perth
showing the pump body..
An interesting thing – I found a square broken piece of yellow
plastic in the bottom of the reservoir tank.. identical plastic to the
plastic wire tie at the top of the white wires seen in this picture..
But I could not find anywhere where this plastic might have broken off…
Odd?? Maybe it was part of the wire tie at some stage??..

The leaked stuff around the inlet manifold is oil from the turbo..

back in place and cleaned.. ie half clean engine bay…
The gleam is from diesel…. Everything got covered in it!
Job took about 8 hours..
Rating = Hard - If you can avoid doing it. avoid it because it was not fun… the brackets that hold the pump onto the engine are very difficult to get to..
