Comments about Melling Stock Replacement Oil Pump:

Great product! Replaced my old pump and screen as a preventative maintenance while replacing rotted oil pan. The pump replacement is not difficult once you get the oil pan removed which is where the real workout is (see my review on oil pan gasket). But some important tips on pump installation:
1) Hand tighten the new screen in. I counted the number of screen threads left outside of the old pump and tried to match that when tightening the new screen unto new pump. The last rotation was very difficult to do by hand but I managed. I would NOT recommend using any kind of tool to do that as you might bend the screen. Just good ol' active persuasion with hard working set of hands! Also make sure to align the screen position EXACTLY as on the old setup (i.e. bottom of the screen parallel to the bottom of the pump)
2) PRIME THE PUMP! Can't stress this step enough! Very important! Pour some clean oil into the screen and keep turning the hexagon knob with your finger until you see oil shooting out of the pump. Then pour a little bit of oil directly into the pump.
3) Wipe pump's mating surface clean, first with dry rag then with acetone/paint thinner soaked one. Apply liberal but not excessive amount of RTV Silicone to the pump mating surface and adhere the new gasket over it, making sure the holes align properly and no excess silicone got squeezed into the interior of the pump.
4) Install the new pump setup. MAKE ABSOLUTE SURE, the hexagon saddle fits unto the shaft protruding from the block EASILY and SNUGLY WIHTOUT ANY FORCE. If it doesn't align, turn the hexagon with your finger to ensure it does.
5) Align the bolt holes and tighten the 2 bolts snugly but not overtightened.

Thats it! As a final word - when you are all done with putting the oil pan&gasket back on, reassembling everything, and pouring fresh oil in - Don't be alarmed when you 1st start the vehicle up and it runs very rough. It will quiet down in a minute or 2 once the new pump gets everything lubricated with oil.

    • Q:

      I have a 1995 Jeep Grand Cherokee V8 318CID with approx. 140 k miles. I have high, very high oil pressure on gauge. Pegged to the high side. I wonder if the oil pump has a pressure release valve built in to allow excess oil pressure to bypass back into the oil pan. also what could happen inside the oil pump to keep the valve from opening causing high pressure.

        A:

        Hi Bob! Glad to be of assistance! The Melling M72 is a compatible part for your Jeep however this part does not come with a pressure relief spring. There is also another upgraded version of the M72 which is the M72HV(High Volume). This HV oil pump support only additional 25% of oil volume and there is no relief spring valve. I would recommend that you check with the nearest Advance store to check on the availability of any alternate oil pump with the pressure relief feature for your Jeep.

        A:

        The problem may be with your oil pan, oil pump or the condition of the bearings. However, I would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not (solve/be) the problem.
