So I'm going to replace the oil pump on the Explorer motor I have. The only one that is motorcraft branded is the "high volume" one with a 23mm input. The stock unit is a 21mm pickup. Will the pickup tube from the high volume one work in my Thunderbird, or do I need a different one? Rock Auto doesn't carry a Motorcraft unit.

Agreed on both counts.
Got a part number of what I should get? Not seeing pickup tunes anywhere. Can I reuse my pickup tube if I flush it?

You won't find replacement pickup tubes for a MN12 pan anywhere. For a stock build, a Melling M176 would be a good pump. Yes, you can flush out your pickup tube and reuse it.

Awesome, mine is a little hotter than stock though, ported heads, kooks, mhs stage 2 cams. The melling still sufficient?

Planning on keeping it below 6500 rpm? What size harmonic damper will you be running?

Yes, it's a fun street car, highest I expect to spin it is 6000.

Running under drive pulling, so the harmonic balancer is smaller than stock. I can measure it if it helps. It's a good one, not one of those two piece ones.

The M176 should be sufficient. If you want additional insurance, the M10227 is a great pump, but I think it's overkill for this setup and would require the '95-98 FN10 pickup tube.

Thank you! I'll get pricing on an M176 and get one ordered.

Flush out the old pickup tube with cheap 30W oil?

No problem. I'd use a solvent. Acetone, mineral spirits, kerosene, old gas...

On the subject of oil systems...

My oil pan has windage baffles, does this make it a Mark 8 pan, or did the Thunderbird have baffles and windage too?

No. The distinctive feature of the Mark VIII pan is the protrusion from the right side (tumor) that holds 1 extra quart of oil, the rest of the pan is otherwise identical to the Tbird, save for the oil level/temp sensor anyway.

Gotcha, thank you!
