[QUOTE="Gilaguy23, post: 436196, member: 19498"] In the same case on my 91 there was no problem with the sending unit, its all in bad grounds at the gauge cluster. Pull it, take it apart, clean all the little contact points and I tapped another ground to the existing cluster ground and everything started working again. I will say the factory gauge does read about 15 psi under what my after market one does. Cant say out of the 4 cj's, 2 YJ's and a TJ the gauges were with a poo far as accuracy if they even worked at all. [/QUOTE]
