Aaron,
My be worth a shot but try changing the oil filter.
When my new engine was being tuned on the dyno all of a sudden we got really low oil pressure.We changed the oil pump and it was fine for 2 pulls.Ended up being the ****ty Fram oil filter that was on there.

Changed it and now all is fine.Needless to say the engine builder sent all his Fram oil filters back.There not that expensive so it might be worth it to change the oil and filter.

Goog luck
John

 

Problem solved!!! Replaced the sending unit and all is well! Thank you everyone for your help!
