Extra Details
Pump Identification
The K30 crankcase does say K30 on some of them. The K35 pump also used the same casting as the K30, but the cylinder bolt holes are in different locations. The K35 is a single-stage pump. So, if it says K30 on the crankcase and has 2 different size pistons, it is definitely a K30.
