Before I install my fuel tank is there a way to bench test the fuel level sending unit?
Thanks Brian |

Neil - so it does sound like a sender issue. Presumably you tried shorting the sender terminal to GND on the gauge to make sure you get "FULL" indicated? 4 ohms or so on the sender sounds OK within error limits, I'd just make sure that 1) the float is not getting snagged, 2) the wires/contacts are clean and 3) and you measure 4ohms or less consistently every time the float is at the top....
- Tony PS. I have a similar qualification to your son. Agreed: It does come in handy sometimes...! (IMG:style_emoticons/default/smile.gif) |
