I am trying to sort out a few niggling problems with my project 7 grey
cab 3CX but need a little help!

For the life of me I cannot seem to get at the fuel gauge sender - it's
in the top of the tank, but how do I get at it? Is it through the dash?
Gauge not working so I want to test the sender - it may not even be
connected.

Where on the engine is the temperature gauge sender? Again it's not
working, but which transducer is it?

Rev counter not working - the drive for it I know comes from the
alternator - I suspect a none standard alternator has been fitted - is
the rev counter drive in the multi-way plug on the alternator, or on a
separate terminal?

AWEM

Aye depends on what year the 3CX is?

temp sender is located on the thermo housing on the right side i think Perki?

Not to sure about the rest Good luck
