Ive got an 85 Chevy c10 350 2wd. about a year ago i had a 350 crate motor installed because it had a 305 with about 300,000 miles on it anyway.theres some things that used to work but now dont. The windshield washer motor will not work ive taken the motor out and it works outside the truck. My voltage gauge stopped working but all of the rest still do fine. Anyway does anyone have any ideas or maybe a diagram I could look at. Ps don’t get me started on leaking fuel tanks ones fine and the other will hold about 3 gallons of gas and leak the rest. Thanks for the great site. Charles
