Here are some pics of the flushing attachment that we build. It has one hose hookup that run to each of the strainers. You just turn on the valve to the engine that you want to run without having to move the hose from side to side.

Here are a few pics of the strainers, fuel pumps, filter heads, etc.

The one thing that needed to be done to the engines was to increase the number of bolts that drive the blower pulley from 3 to 6. The accessory pulley mounted to the balancer with only 3 bolts. The blower pulley than attached to the accessory pulley with 6 bolts. However, the 3 bolts in the accessory pulley were driving everything. So, I drilled and tapped the balancer and drilled and counterbored the accessory pulley.

The circled holes are the ones that we drilled and counterbored.
