<font color="teal"><b>At Billing John215 checked out my fuel gauge and was at the thought it was this a fault

as the fuel lights works fine and the wiring looks ok

I was thinking of doing what I did with my Temp gauge and replace it with an independent one, ok you have to cut the back of the dash

but I am not bothered with that, better reliability is more important.

I am looking at this one, will this work??

I note the Specification:


#9702;Fuel gauge parameters: 0 --- 0-10 ohms
1/2---90 ohm
1 full-bit - 180 ohms

Thanks for any help</b>

Fuel gauges hardly go wrong, I'd check the tank sender first.
Fuel light gets its signal from a different contact.

I'd second Beans comment. Check the sender coil+connections first.
The warning light gets its signal path via its own connectors...
Only the float (also suspicious btw - if you haven't upgraded to the soldered brass one from US Ford)
and arm are common to the two.

I also agree.
Thru many years of (various) wedge ownership, I have never had a fuel gauge go south. It was always either a corroded connection, loose/broken wire or terminal, fuel sender or associated components. More than once I replaced a fuel gauge with a known working one only to find it was a severly corroded sending unit (current 7) or corroded terminals (previous .
Not saying your gauge is in fact not the culpret, just expressing my own findings.

This post tells how to check to see if the problem is the sending unit.

Hate to be different but when I got my car the gauge only read full with the ignition on (0 when off). I checked all the connections but no joy (must admit I did not take out the float unit but it looked pretty new). I swapped the gauge for one from an ebay 'spare' dash purchase and it has worked fine ever since.
