The Autometer gauge/sender fixed the problem. I'm at about 12.5-50 after warm-up.
The reason i didn't go with mechanical is because i don't like running high pressure hose into the cab. If i were to run it I'd have the gauge mounted on the cowl or around there. But because I live in the ghetto, and it's my daily driver, I don't want some delinquet to come and steal my nice little gauge from me. Also, if it were to get stolen from inside of my pickup then i'd have a big mess. sucks i gotta choose my mods wisely
because of what may happen.
4incht100: check your wiring over again, and then make sure you have a good ground. in the sunpro manual it says not to use any teflon on the sender otherwise the sender could have a weak ground.
thanks,
