to the club. I believe the sender unit comes as part of the fuel pump assembly, although I may be wrong.
There are always people breaking cars on here, so have a look in the items for sale. Alternatively, it might be worth taking a trip to a breakers yard.
Are you sure that all the multi plugs are connected that go to the fuel tank? There are two under the car (one is for the fuel pump, the other is for the sender unit). I would also check that the connections are clean and secure.
any multi point injection fuel pump/sender unit will fit and work its only the single point injection pump thats different but the sender unit itself should be the same
so you would need to fit your own fuel pump to the sender unit
