Gifu's pump is a Bosch VE rotary distributor-style pump. as are all the Onan L634T and Cummins 6AT automotive version engines. The Stanadyne pumps that came on the industrial versions aren't inline, they're also distributor pumps, the DB2. Pretty much the same pump as mechanical-pumped 6.2 GM and IDI 6.9 and 7.3 Fords, except the governor is set-speed, instead of min-max. That's why the Stanadyne doesn't work for running on the street.

Those are the only two pumps that came on these motors.

My industrial L634T came with the Stanadyne DB2...I swapped it for a VE. What's your motor in, ridgerunner?
