In Reply to: help! need a fuel pump part # (NAPA?) for 1965 WM300 posted by Aaron A. Arnold on November 04, 1999 at 12:37:53:
Here's from the listing I have, only the 1/2 ton is posed but aren't they the same? Regards WAW
The correct part number is AC Delco 587 for my 48 Dodge 1/2t at Carquest for about $30-40.
M-37 Fuel hose (from valve to fuel pump, M-37) NAPA11089
WM300 Fuel Pump Contact Mitchell Motor Parts 614-875-4919. The pump that I located at Mitchell Motors was $129.50 plus shipping, and it was new. My truck is a '61 WM300, and the fuel pump that I worked on today is a Carter model 684. (Original)
You might find an AMC car (Pacer/AMX/Gremlin/etc.) from the 70's, as they had vacuum pump systems, or a M151A1 Mutt jeep pump has a vacuum assist.
