New Fuel Gauge....
I need a new fuel gauge, to go along with my cheap sunpro gauges i have...Does anyone make one that uses the same ohm range as my 78 F150 does?
I was also wondering, was that a resistor on the back of the original instrument cluster? That little box thing that the printed circuit for the fuel gauge runs too, its like the size of a tootsie roll?

The gauges won't function correctly if its not working right.

I tryed using the guts out of the old gauge and siliconed the new sunpro face on to it...but i dont think its gonna work because the sunpro has just a little bit larger sweep

If you're using the "guts" of the OEM fuel gauge then yes, you need to keep the IPVR for that one gauge only. The other (aftermarket) gauges, if they're electric use a full 12v for power, if they are mechanical it doesn't make any difference.

Pick out which gauge you would like to use and contact the manufacturer and ask them if the gauge is compatible with the stock sending unit.

The stock sending unit out of my truck? Ok, but do you know what ohm range our sending units use?

Thats correct. According to the shop manual, full is 8-12 ohms and empty is 60-86 ohms so 10-70 ohms is right in the ball park.

Hey mike....what about this gauge? I know it has a 0-90ohm sweep, but this is the only closest ohm range gauge...if it put it in, and hooked it up, since it has a larger sweep, wouldnt it tell me(when its truly full) that it would be just under full and (when its truly empty) it would tell me i had more?

I don't know if this would burn out the sender or not, my guess is it would but not sure.

The 0-90 gauge will give the opposite reading as the OEM Ford gauge which is 70-10, EMPTY TO FULL.
So, in other words with a full tank of gas the gauge will say EMPTY, as you drive the gauge will progress to FULL.
Wish it worked in real life like that.
The 0-90 is the Chevy system. Ford is opposite.
