Can someone please help me locate the oil pressure sending unit for my truck? Asap? Ive never had to changed one before and I am too scared to drive my truck til I change it...Ive got my Chilton but the diagram isnt very clear and there isnt any videos on youtube to show it for my vehicle. Its a 1993 s-10 blazer. 4.3L. If you have a picture that would be the best help for me, but Ill take whatever help I can get! Thank you in advance.

 

its a black can looking thing. Behind the engine,on driver side of distributor usually mounted sideways buried deep down under the plug wires. Its hard to get too without removing the distributor and other stuff in its way. Are you having oil pressure problems with the gauge? first off make sure its got oil. if a new one doesnt fix it,you need to get a mechanical gauge and check actual pressure. if its low sounds like engines tired.15-20 at hot idle is fine. should rise to 35-45 at throttle.
