Default XJ Oil pumps

im looking to boost my oil pressure back to closer to normal ranges--

cold idle pressure 40+
after a 30 min hiway drive coming to a stop at idle pressure drops to 0 (and can hear engine starving for oil)
rev engine up to 2K pressure is at 20



i thinking my current pump has some wear with currently 140K miles or it could be the pressure relief spring in the pump that is worn out
as a last resort i was thinking about replacing the crank bearings

would a i need a high pressure pump OR hi volume pump?
