Hey all,

Working on a 1965 F100 240 I6 that has recently started having problems keeping oil pressure. The gauge and idiot light seem to work fine, and are indicating that the oil pressure is low (below 10). So I think those are working fine. However, when I've tried to find the oil pump itself I'm having a hard time. I've found some diagrams and part numbers online (pic related) but they don't seem to match the part I have (from Melling) or the part numbers from National Parts Depot. Can someone please give me a hand with this? Thanks!

This is the part that I bought from Melling. They said it's for my engine, but I can't match it to any of the diagrams for the life of me...

 

Not really sure but it should be driven by the distributor.

 

The oil pump'' and pickup tube should be in the oil pan?..pic's are not showing the oil pump, unless there is a different setup on inline six, you have to remove the oil pan to get at the ''oil pump''
