Facet square fuel pump expert required

[MarcNS]

I am re-fitting my fuel pump due to a small fuel leak and now have a bigger problem.

 

Problem is when undoing the bolt to the pump connector the chamber bolt undid - me being stupid wanted to see what was inside

 

and inside found a large spring, a small spring with a dome shaped piece of plastic with a pin for the smaller spring and what looks like a diaphragm/valve.

 

I have set it with the dome shaped piece of plastic against the large spring in the chamber, next is the small spring and then the valve, which is inverted and seated in the base of the chamber

 

Does anyone have an exploded diagram of a facet pump as when refitting it doesnt seem to be drawing through the fuel?

 

Many thanks,

 

Marc

Have you got a part number?

 

Have you tried Google Images? The top link leads to quite a lot of exploded diagrams.

Thanks,

 

I have a 3-4.5 bar square facet fuel pump.

 

still trying to find the internal working of the pump on a diagram.
