I just purchased a new to me 87 manche short bed that was originally a 4 cylinder. It was swapped over to a 4.0ho out of a 93 xj donor. The fuel guage is reading backwards and after some researched learned all about the ohm readings changing and how they flipped polarity around 1990. I read mention of flipping the wires behind the guage or at the pump itself. Not sure what is best.
Also how or what did they do to make the pump work for the 4.0? You can't buy an MJ pump from what I read and swapping in an xj pump I also read doesn't work.
I don't care if the guage doesn't read that accurate I just want to be sure I habe a 4.0ho pump and the guage moves in the correct direction. I'm going to pull it out this weekend but I'm not sure what to look for.
I read somewhere AutoZone sells a pump assembly that works in a MJ tank without the pan in it. What years/style have pans in the tank?
Thank you in advance for your help
