Title: 1988 90hp Johnson Vro
Post by: jdupree on June 23, 2006, 04:51:05 PM

Is the fuel pump and vro pump the same unit on this motor.  If so, how do I remove the fuel pump.  I think it is bad.

The fuel pump is well, the fuel pump. A VRO is a an oil pump that regulates the oil flow into the motor.

Variable ratio oiling - in other words oil injection.
