Good bang for the buck.
Why waste time on cleaning an old housing when you get this replacement for so little money. It fits great and looks much better on the engine.

Review shared from Engine Oil Pump Kit (91-06 2.5L & 4.0L Jeep Wrangler YJ & TJ)
2004 Wrangler - EricrWI
Oil pump
Excellent quality, gasket included. You do need to install the sump and screen assembly to the pump, which is somewhat difficult, I used a flaring clamp to tap it in, and it helps to heat the aluminum receiver on the pump with a torch to expand it.
