[Robert Betts]

Hi does any one have a diagram of the fuel pipes to and from the fuel sender unit please . On my car I have three pipes coming off the sender unit the carpet behind drivers seat . Yet from the fuel filter under bonnet I have one inlet and one return pipe ....Not sure if I'm getting pressure from in tank low pressure unit . just need to test correct outlet pipe

thanks

If memory serves correctly you have feed,return and vent. The feed and return are identified by arrows and the vent has a V.

Canââ,¬â,,¢t remember which way round they went but seem to remember the vent pipe was a different colour,quite possibly they would only fit one way aswell?

Now you mention the boost heater it is obvious what the 3rd line is,when I had mine out it was identified V on top of the sender so I assumed vent.
