Fuel Pumps

[PhilNW 66]

Just replaced my fuel pump with a Bosch one I bought years ago when I thought they might me getting hard to get hold of.

 

Just been looking and Bosch ones now  look unavailable

 

Has anyone found a supply of Bosch and if not what are suitable/good replacements?

Thanks mei

 

The one I am replacing in post 90 Bosch part no 0580 314 075.

 

Any links to lookup the equivalent?

so the bare pump inside that is originally a  0580453052, an 0580 314 075 is apparently the superseded part, however I can;t see any available.

 

a walbro GSS342  is said to fit, never tried one myself as yet.

Yes, I've fitted several  GSS-342K into the white carrier. It's a fairly easy swap. Not so into the black one however.

Hi Peter

 

Any problems with the existing standard fuel pressure regulator and the 8? bar the walbro pump can produce?

you'll just get more fuel flowing down the return.

The pressure is determined by the spring in the fuel reg. The Walbro pump is just capable of handling that much pressure. An oem pump starts to make strange noises at approx. 6 Bar in comparison.
