Replacing HPOP

I will be installing Stealth's srp 1.1 as soon as it arrives, does anyone have any tips or tricks they could share that would aid in the installation process? Also, is it recommended to change the ICP sensor or IPR valve at the same time? The truck has 151xxx miles on it.

What made you decide to go with the SRP 1.1? I am doing reseach for my upgrades next year and HPOP is on the list. My HPOP choice so far is between the SRP1.1 and the Adrenaline from DieselSite.

Thanks

Steve, Thanks for the advice! I'm thinking I might use the stock IPR for nor now unless it turns out to be bad. What are the symptoms of a bad IPR?

Rascal, Stealth was able to increase internal displacement by almost 37%. By adding new larger billet pistons and cylinder block combined with a new 17-degree billet swash plate. The pumps are designed with dual ABEC-5 ball bearings. They replaced the rear cover tapered section snap ring with a spiral lock retaining ring. A new billet rear cover is installed that has a raised o-ring boss. They machined the 3 high-pressure output ports from #6ORB fittings to #8ORB fittings and also machined the edge filter plug in the bottom of the pump and taken it from a #3ORB fitting to a #6ORB fitting. They also machine some of the internal passages to ensure proper flow in and out of the pump.

What about just changing the mechanical portion of the IPR? Dieselsite offers that option for $75

That would work I had mine stick on my srp1.1 and had 3900 psi at idle and then it found a weak injector oring and lost all icp. Watched it all happen on the scanner, I unplugged the ipr and it stayed running for about 15 more seconds then popped the upper oring on the injector. It's a 99 with 150,xx and that was the first an injector has ever been out, so I oringed all 8

Works good so far with stock sticks, thinking I should have 250/200's by April so I'll see how it goes then, I don't think I'll have an issue

Why would you want 200/200? just get 250/100...will empty out in 2.5ms and have better injection pressure= less smoke more HP and MPG's.
