I have a 1988 D150, 2WD, w/ 86000 miles, and its in good condition. My OIL PRESSURE GAUGE is always 1 or 2 marks from the "Lowest(L) Point". Should I be worried at all. How do I fix it? Thanks. :gr_patrio
My 87 had a bad sending unit fron the factory when I got it new. Turn the key on and it showed pressure before the engine was cranked. New sending took care of that plus showed more pressure while running. :gr_patrio
depending on what motor i think they are right on the back of the engine. Remove the air cleaner and look around the distributor there should be a sender with a small wire connected to it on the back of the engine block.
try avoid the mechanical senders and guages that require a small line that sends oil from your block right to the guage in your cab i dont like these they get air locked sometimes and arent accurate and or the plastic line breaks and u get oil everywhere :VHOT:
