Driving down the interstate, the oil pressure dropped to zero. stopped the truck and cranked back up and it was way above normal. did this a couple of times. is this probably a sender? Can I test it? where is it located. can i put on a mechanical gauge to test it? where is the best place to tap in at? Sorry for all the questions. Just a little frustrated.

there is a 1/8 npt plug on the top of the oil filter housing best places to put a mechanical gauge

 

My oil press gauge goes to high whenever i just turn on the key. Is this sounding like the sensor??

 

it could be the sendor is going bad

 

Not a lot of oil pumps go bad in these trucks, like ever.

 

just put the mehanical gauge on it and pressure is great. Is the sender the sensor right beside the filter?

Yeah, like a little below it?
