If your going to change out the oil pump get a oil pump from a dod engine they put out more pressure then a hv pump 18% is not much hv. Oil sending unit might be bad change it out for $50. Yes you can reuse gasket on the pan if you dont want to reuse gasket drill out the 2 rivets that hold in place send the $50 and buy a new one...

cradle comes down to swap the gasket.

DOD "DISPLACEMENT ON DEMAND" ENGINE's THE OIL PUMP's PUT OUT MORE OIL PRESSURE THEN A NONE DOD... YES IT WILL WORK WITH YOUR LS ENGINE ALL PARTS ARE INTERCHANGEABLE FROM A 4.8-6.2..

Also the dod "displacement on demand" oil pumps put out 35% psi more then a none dod oil pump and a hv oil pump puts out 18%.so the dod pump is the way to go.
