Core Pre-Ship Only, Turn Around 7-10 Days

Terminator Engineering - T500 HPOP


Tired of your 15 or worn out 17 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 modified with all new seals and o-rings, tested and ready to install.  Please indicate whether you are sending in a 15º or 17º core 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. Do not include your IPR with the core, or HPOP lines. 

The process begins with you purchasing through the website, then shipping in your core to the address on the core sheet. The HPOP Core sheet 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. Mounting gasket is not included with the order, but is available below.

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.

    Leak-Free Pump

    Posted by Unknown on Jun 19th 2022

    Sent my leaky old pump for my '01 in and moved up to the T500. Now I have no leaks, and it runs my 175/100 Rosewood injectors to their full potential.

    Best hpop you can get!

    Posted by Cole Tara on Dec 25th 2021

    My 7.3 needed a hpop as the original one was tired , sent my old core in and 2 weeks later got the new t500 hpop, pretty fast considering I live up in Canada, this hpop is one of the best things Ive done to the truck so far, my truck is able to blast up hills and keep its speed , runs amazing and starts instantly now!
