55-59 fuel gauge with mustang tank
 

Hey guys I’m building my 56 Chevy truck and I’m using the stock gauge cluster. I’m using a 69 Ford Mustang fuel tank. What do I need to do to make my fuel gauge read correctly? Thank you

The goal as far as I'm concerned is to make sure the gauge reads most accurately at low levels. Thus if possible, fill the tank 1/4 full. 4 gal for a 16 gal tank, 5 gal for a 20 gal tank. Per the following pic, if it reads too high you bend the float arm B upward at the elbow C, which causes arm A to pivot downward. Little tweaks at a time.

Now if you only lived near me, I could tweak your sending unit using the above setup, without putting any gas in the tank. Yes, I use to restore M00stangs.

This is what you need ,this will fix miss matched ohms from sender which is 90 ohms full. Gauge is 30 ohms. full

That unit from Speedway may be a good investment in that the 69 Mustang has a 10 to 78 ohm sending unit according to this 69 Mustang group page. http://1969stang.com/forum/index.php...uge-do-i-need/

I've got a 74 F 150 tank I am thinking about using in my 48 and that unit would really help on it.
