just replaced the vro pump now it runs for a minute then shuts off pump the ball it starts up runs good if i keep pumping the ball the motor runs good it ran fine before i changed the pump. it was the oil side that was bad on the pump. i can't figure it out can anyone help ?
 
Make sure all hoses are going to the correct ports.------There is not much that can go wrong with the oil side as it is a metal piston with an o-ring.------What happened after the oil side " failed " on this motor ?-----What does a compression test show on this motor ?------Stop running this motor or mix 50:1 in the fuel tank until VRO is confirmed to be working.
