YES! this is the pump, I thought I had a problem with the gear binding. after talking to Melling, I was made aware that I was turning the camshaft with the sprocket bolt and with out the timing chain installed. The cam was being pushed to the front of the engine and giving the feeling of a bind. However, I was convinced by others on here that I didn't need a HV pump. I put the original pump back on with a new gear and until I talked to Melling, got the same feel of a bind. I installed the crank shaft (no rods or pistons and timing chain and the binding went away, just like I was told that it would. If someone bought this pump and had a problem with it, I would make good on it. Your lack of a narrative in your reply "is loud and clear."
