New hpop

[millwrightdude]

I'm wanting to replace my hpop, I'm wanting something a little better than stock. Which one should I get and why?

I had plans to call him, I think I'm leaning towards one of his

I went with the Terminator T-500. It was lower cost than the others and Joey has an awesome reputation in the "oil world". It made a heck of a difference and the truck pulls strong now. ICP holds 2800+ on long pulls with my trailer. IPR duty cycle is usually around 50% when pulling hills too. Watching my Aeroforce Scangauge, I can easily get 3,000 psi when rodding around.

Another vote for the T500. Joey is top notch.

How well will it work on a stock truck?

The T-500 will work great with a stock truck. Many of the older trucks with a 15 degree HPOP really notice the difference. The 17 degree HPOP's don't show as much as a change as the 15 degree units, but do very well with the added oil pressure and volume. The stock HPOP's will fall off when the demand gets placed on them, the upgraded HPOP's continue to provide the needed oil.

I run stock injectors and it is a world of difference. I had a pretty good pump on mine when I changed it. The T-500 really woke it up and also increased the fuel mileage a bit. Having more volume and pressure in the oil system is valuable to any truck.

Have you checked your ICP and IPR duty cycle while driving? From what I have seen, most good pumps will hold 2800 psi under acceleration. Average trucks hold about 2500 psi, and weak trucks may only hold 1800 psi. Changing nothing more than the HPOP you will be able to hold 2900-3000 psi. Your duty cycle will also be less!

Only pump that has a lifetime warrenty is the SRP1.1..rest 90 days..

I also should replace my HPOP. Truck has 225K and it is leaking. I have kept my engine stock except for the upgrades list in sig block. So tell me exactly what I need to buy for the replacement. Sure I need the pump but do I (should I) get a new IPR? Gaskets? O-Rings? What should I have before I start pulling stuff apart? Also, with my early 99 I guess I have a 15 degree. I only see 17 degree replacements. That is what I should get right? How do I check the ICP IPR duty cycle?

Thanks in advance for the help.

If you are replacing an HPOP, all you need is the HPOP, If you order a T-500 you get the gasket. You really don't need to replace the IPR if yours is good. It may be a good idea though. I would look at getting new HPOP hoses at the same time. Not required, but I have seen more and more posts where they are failing. Being that all trucks are pretty much 10 years old now, it is also cheap insurance to keep from getting stuck on the side of the road.

Here is the T-500, HPOP Hoses, and IPR for you. Here is an How To on swapping it.

woodnthings8 nailed it. All you really "need" is the HPOP gasket...but when I did mine I went ahead and changed out both HPOP lines as well since I had over 300k miles on the originals.
