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 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. You do not need to include your IPR with the core, or HPOP lines. 

The process begins with you shipping in your core. 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

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.

    Great pruduct for a great price. My truck has much better start ups now since its been installed. The engine feels so much smother.

    No problems so far, this is is the first t500 I have used, Bosch didn't last 13 months and started to leak.

    Excellent upgrade. For the money it's one of the best mods done to the truck so far. This pump has woke my truck up! The T500 is far superior to a stock hpop

    Riffraff is an awesome company. Friendly, helpful, and knowledgeable with both great prices and great service.

    T500 hpop

    The good. The pump is awesome! Even with stock injectors and few upgrades the pump made a huge difference! Just installed it, so not sure on longevity.
    The bad. If it really is anything, but the truck seems to have a little lope and it will cackle. Briefly. At idle. Not sure if this normal or a sign of something else.
    On the whole, the best bang for the buck for sure. It really woke up the truck. The stock air filter isn’t cutting it anymore. I did the 6637 mod. Much better.

    installed on 2000 7.3 with 230/80 rosewoods, seems to be a good match so far, more pressure at lower rpms= more power

    Great pump! Great service!

    I will say to make sure which ever year pump you need for your truck you need to send in that year core but otherwise great pump and service !

    I have 250cc/200% full force injectors and this pump has been supplying them fine for about 3 years now. Would definitely recommend.

    Truck runs smoother and idles quieter than stock. My 185 cc single shots don’t require aftermarket hpop but even so it makes a huge difference.

    Works as expected, seems to be well done, ordering process is a little complicated, wish there was someway to communicate with the repair shop. I would use them again
