Fuel guage questions.
 

I want to put an aftermarket fuel guage in my Jeep. The tank I have is from a 94 Yj. I believe the sending unit has 33 ohms full and 240 ohms empty. Can anyone confirm this? The tank is probably about 3/4 full right now and I get a reading of about 100 ohms.

Also I want to make sure I am testing it right. On the back of the guage I have now (it is the wrong one thats why I want the correct one), I have a wire from the sending unit, and what I believe to be a ground wire and a 12v power source. I went to ground and to the lead from the sending unit which gave me my reading of 100 ohms. Does it sound like I did the right thing?????


:confused:

It sounds right but you could all ways call auto meter or something like that. They would know the best since I need to do the same thing at some point
