    7.3 powerstroke ipr block off tool

    Works as advertised. Well made. Was able to dead head hpop. Advise using a length of hydraulic hose to hook up gauge as a pressure cushion because the pressure comes up very quickly. Without the hose my 3000 psi gauge was immediately pegged. This could damage a positive displacement pump without a pressure relief valve.

    This is a great tool and has saved me time and not money. I thought my adrenaline pump had failed and was going to send it back for warranty but couldn't really have the truck offline. Saw this tool, and figured I would give it a try. Used it and the truck fired right up, so now I know it isn't a bad pump. Still digging but now at least I know I am not waisting time swapping out an HPOP for no reason. Recommended for a fast answer on if your pump is bad.

    This makes testing the HPOP so much easier. I have needed one of these in the shop for years!
