[axeman]

driving home this evernig the fuel gauge just droped as if the inigtion was turned off. i have cheaked the conections on the sender and cleaned them and reinstated the conection to the sender, the temp gauge is working as it should do. as i think they are related.

has any one got any ideas?

Check the multiconnector at the the rear of the dash and give the connectors inside the plastic housing a good inspection along with the copper strips that it slides onto. If all appears OK, You could remove the wire at the fuel tank sender and take a resistance reading of the fuel sender (the reading will depend on how much fuel you have, e.g a third of a tankful should read around 100 ohms. No reading or very high suggests the sender is open circuit and needs renewing. Alternatively, link the wire to a good chassis point and then switch the ignition on and see if the gauge needle rises. I would measure the resistance at the dash multiconnector (as it is easier to get at and you will probably have it removed to check anyway) by placing a multimeter across the relevant pins, e.g, a post '86 van would be pins 3 and 7 (if I was absolutely sure that the connection at the sender was ok, not corroded, covered in crud, etc!). It could be some other fault but I would eliminate the multiconnector and fuel sender first.
