Yes, that is the part number that I posted. Usually you cannot post a link to a NAPA product (Hotrod Lincoln's link does not work for me - it has a "personal session" code that will only work on Jerry's computer).

Here is the information from the NAPA site:

Oil Pressure Light Switch
Product Line: Mileage Plus Electrical
Part Number: MPE OP6626SB
Price: $5.89

Warranty Limited 12 Months
Attributes # Switch Terminals : 3 Terminals
Oil Pressure Switch Pressure Rating : 2-8 PSI

------------

3750x2 is mostly likely the T-fitting that will work.

NAPA: WH 3750X2 (search on NAPA site: 3750X2)
