I tried Cummins Northwest here in Seattle and they said the "1 spacer to move pump out 1/4" - 3914284" part number - it's gone obsolete.

I got the pump, line etc., but may have to make my own spacer iunless someone has a better suggestion.

Norm, they have an 800 number but I don't have it with me. Regular number is 707-725-3307, ask for Brad.
