Primus pump/electrical mod

[Ralph L. Fullenwider]

Hello everyone:

Have just modified the original Primus pumps to a more available Groco
CP-20-BBC, the type used in the older Birds for Chassis heat.

A write up on the pump, electrical changes needed for the increased
amperage and photos have been added to the files section.

This mod was done to Bim Burt's '91 PT40WB

Safe travels,
