So I have an 88 k1500 with the 350 that the previous owner removed and rebuilt... Didn't hook a lot of stuff back up etc... It's like a puzzle. It runs good for the most part but the oil pressure gauge in the cab pegs out when it's running. I've heard 1989 and older 350 engines have 2 oil pressure switches/sending units. I know about the one up by the distributor. But can't seem to locate the other one. Could someone help me. Also what does the one by the distributor control? And what does the other one control? If anyone had some pictures of where the other one is located that would help me immensely. Thanks in advance.
