I noticed oil splatter on the underside of the hood being thrown up by the fan. Crawled underneath and saw a couple oil drips on the bottom of the fuel pump between the two screws. The tie rod was also soaked with oil. I did not see and apparent oil coming from above the pump. The pump does not have that many miles on it.

Could the pump be leaking oil? What other things to check? Thanks

Check for gasket failure at the pump plate and the pump mounting bolts. Also, is the bolt in the front of th block in place and tight? The one you can use to hold the fuel pump pushrod when you replace a fuel pump. If it's not obvious, clean everything spotless. Go for a drive and see what you see when you come back. Dennis

I had that issue after replacing mechanical fuel pump with electric. Problem was as stated above ^^^ Left the bolt out

Bolt is in and was sealed.

leaves few options... either the adapter plate gasket or the fuel pump gasket. unless the pump housing is cracked, I don't see how the pump itself can leak except where the pivot pin goes though

Just because a part has low mileage or limited use doesn't mean it can't fail prematurely....lots of crappy rebuild jobs, Chinesium kits, bogus "refurbished" pieces out there..

What's so hard about reading the 1961 Passenger Car Shop Manual....page 10-66 in the "Fuel" section:

Troubles and Remedies
Leaks: Oil:

1. Hole in diaphragm
2. Leak at mounting gasket.

Change or rebuild the fuel pump and then change your engine oil; do this before you spew enough gas into your oil to dilute it and gall your cylinder bores.

Boom - done!

If it's not leaking externally then the diaphragm is ruptured or the upper shaft seal has failed. Pull the dipstick and smell the oil for fuel contamination. Are the pump weep holes full of oil?

Thanks for the info guys. Can't remember the easiest way to R&R the pump. Is everything accessed from the bottom? On my '65 I removed the
tire and had easy access to the bolts and pump.

Removing the tire doesn't hurt and may give better access.
Try to get the engine to TDC before removing the faulty pump...it'll make installation easier...

Make sure the hole used to secure the pump rod during change was plugged, short bolt.

Is everything done from the bottom? Need to position the car in the now full garage!
