Terminator Engineering - T500 HPOP


Tired of your 15º or worn out 17º pump? Need a little more volume for those new injectors?  This Terminator Modded T500 pump is what you need and won't put a dent in your mod budget.

We ship you your pump with all new seals and orings, tested and ready to install.  Please indicate whether you are sending in a 15º or 17º and if it is out of a Super Duty or a OBS. Be sure to include your pump fittings as they will be resealed and sent back with the pump. You do not need to include your IPR with the core.

Click Here for the HPOP Core sheet the must accompany your core return, and must be shipped to the address at the top of the sheet. If your core does not have the core sheet and/or the HPOP line fittings aren't present then your core will be refused and returned. Due to increasing costs mounting gaskets are no longer included, We are sorry for any inconvience, but we do offer them still for purchase.


Warranty: 2 year

Currently we are only accepting pre-ship orders, which means you have to send a core in first to be built, Terminator modifies it and then ships it back to you

IMPORTANT* Terminator Engineering Terms for pump warranty. If you feel you might have a warranty on your T500 and you have diagnosed it isn't the IPR, Injector poppets, Injector Orings, or IPR Pigtail please send your pump back to Terminator for warranty. If pump is tested and flows Terminator will require you to pay return shipping on your good pump. If it is a confirmed warranty Terminator will correct and return the pump.  This warranty is only a manufacturer warranty and is not serviced or applied through Riffraff Diesel. By checking the box above you are agreeing to abide by these terms that Terminator has set forth.

  6. Riffraff was great... 3 Star Review

    Posted by on Nov 22nd 2016

    Terminator sucked taking so long to turn it around. It isn't Riff raffs problem as they have always been great on all my orders.

  7. Exactly what i needed 5 Star Review

    Posted by on Oct 18th 2016

    Pulled original hpop off to reseal amd reinstalled and to no luck the pump gave up the ghost after diagnosing the issue with AE. Sent hpop off to get terminated and couldn't be happier. Not only due i have better throttle response the truck fires right up. Evidently my original hpop was on its way out for the past 40k miles as the starts were getting longer and the truck felt sluggish. Not anymore,my early bird runs great now. Had pump sent off on a Monday and it reached its destination on Thursday. Had my newly built hpop back 10 days later.

  8. First mod you should buy 5 Star Review

    Posted by on Oct 6th 2016

    Was getting 1800 psi on stock setting and 1200 psi with my chip turned all the way up just had no power and would black smoke for days took about 9 days from when they got the pump to when it arrived to my door once all the air was bleed out I was getting over 3000 psi with my chip turned all the way up and made the truck completely different now I just need to fix the posi trac so it will stop boiling one tire

  9. Better than stock pump 4 Star Review

    Posted by on Sep 28th 2016

    Had to get a new HPOP, decided to go with a T500 rebuilt. Great value for what you pay and what you get. Pump is a 5 star, but they took 15 business days to rebuild it, when the website says 12-14. I called Clay and he said that was just an average time, not a big deal but the website doesn't say that is an average time.

  10. Noticeable change in Excursion 5 Star Review

    Posted by on Aug 27th 2016

    Truck runs better, stronger, faster and is quieter at all rpm's. I sent my HPOP in on a Monday and received back a T500 on that same Saturday.
