    Tim- I can't help you with your gauge problem, but I'd like to say, "WOW WHAT A TRUCK!!!" That is another awesome job well done!

    Sorry about the "well done" part ANDY... Crap- I can't even get my barbs straight... I'm sure steve was wondering what the heck I ment!

    There has been quite a few discussions about this problem so if you go to the "search" you should get lots of help. Basically, if you ground the sending wire the guage should read full and if you disconnect the sending wire the guage reads empty. If it does this, your dash unit is OK and it's in the sender or wiring. You need to use a Runtz resistor on the voltage feed side of the guage if 12 volt. If run on 12V without a resistor it's probably toast or soon will be. Your truck is a beauty.

    Other way around. If you ground the wire going to the sending unit the gauge should read empty. Disconnected it should read full.

    Mr. Hanlon would be correct.

    The gauge will read full when disconnected from the sending unit if the gauge is working.

    Thanks for the advice

    and the nice comments about the truck. Got the bed put on now, waiting on the hood. It has been 4 yrs! I am heading to a show Mar 23, 2007 so we will see how she fairs!

    Keep checking the site as I will update often.

    Tim ;

    The others have covered it .

    You need a 100 % _perfect_ ground at the gauge itself for it to be accurate
    I prefer to run a two wire harness from the sender to the gauge head in the dash and I also like to add ground wires between the dash pods to the cab abd from the cab to the frame....

    Many nice webbed ground straps in the junkyards to do this and make it look factory or just hide 'em .
