    This thing helped me quickly figure out that it wasnt my HPOP that was bad. like I originally thought. In the end it ended up being a bad IPR pigtail. This saved my $800 buying a replacement HPOP. Thanks guys!

    Havint used it yet. But I know it will work. Solid metal plug no doubt it will work. Will also fit some heui international engins and CAT heui engins. I did verify the fitment on a maxforce 10 pump we have at the shop.

    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.
