    Terms & Conditions

    We at Diesel Power Products offer a deferred core program in which we allow you to defer the typical upfront core charge when purchasing via credit card payment. All cores, whether the core charge was deferred or not, must be returned within 21 days from delivery date of product requiring core charge. Failure to do so can result in forfeiture of the entire core charge return. In the event you originally deferred the core charge, you authorize Diesel Power Products to charge you for the core charge.

    All cores must be returned to the original warehouse that original shipment was sent from. If a return label is provided in the original shipment, use this tag. If one is not included, contact us immediately, and we can provide you with the correct address of where the core(s) must be returned to, as well as an RMA (Return Merchandise Authorization) number. DO NOT rely on the return address on the original label as a source for where to ship to.

    If cores are shipped to the incorrect warehouse, your core money will be returned less the shipping cost for us to send the core(s) to the correct warehouse, or if you deferred the core you may be charged for the shipping amount.

    Cores that have been disassembled and/or have missing and/or damaged major components will not receive full core credit. Returned cores must be on a "like-for-like" basis, meaning that the returned core has the exact same fitment as the remanufactured component that was purchased. In the event that the core is not "like-for-like," your core may not be eligible for return / credit.

    Diesel Power Products has the right to alter this policy (i.e. extend the terms) for any reason. If you have an outstanding circumstance, contact us.

    What is a "Core Charge"?

    In order to understand what a core charge is, you must first understand what a core is. In the automotive industry, most products are manufactured from brand new materials. However, numerous products are also remanufactured, meaning that the manufacturer of the product takes a used product, typically removed from a vehicle, disassembles, and replaces all worn components of the master product. A great example of this is in regards to automatic transmissions in which the manufacturer takes an existing transmission, replaces all of the inner working components, such as the torque converter, valve body, etc. and merely reuses the case.

    Because aftermarket manufacturers require a steady stream of incoming cores to build, they charge a deposit on the core, known as a core charge, that is refunded upon receipt. In some cases, the core is not reusable, such as in the event of a cracked case, at which point the core deposit would not be credited as the core component is not reusable.

    If you plan on returning your core you have two options.

    OPTION 1:
    You can accept it, which means you will be charged for the part AND the core at time of purchase. You still have the option to send it back, and if you do, the core will be refunded back on the card used, presuming the core meets core criteria and the core is returned within 21 business days from originally receiving your order. If you have outstanding circumstances that would not allow the return to occur within 21 days, please contact us.

    OPTION 2 You can defer the core charge. If you defer it, you will not be charged a core at time of purchase. You will have 21 business days from the day you receive it to send it back. As long as the core is received within the 21 business days, you will not be charged. If 21 business days goes by and you do not send it back, the card on file will be charged the core amount. You still may send it back, and once received, we will issue the core amount as in store credit, pending any limitations as set forth by the manufacturer.Core deferral is limited to payment by credit card only.

The High Pressure Oil Pump, commonly referred to as the "H-POP" found on your 7.3L Powerstroke is like the heart of your engine. It is responsible for pumping oil (obviously) but this pressure is what actually creates the pressure to drive your injectors, as well Thus, if your HPOP is unable to keep up with the demands of your truck because of age, larger displacement injectors, programmers or chips, your truck will never be able to realize its full potential!

The Adrenaline HPOP from DieselSite is designed to cure the dreaded P1211 code that is so common with 7.3L Powerstrokes, as well as just general injector starvation that many do not even realize is occurring on their trucks, literally robbing horsepower, fuel economy, and reliability. These pumps are completely rebuilt and are designed to deliver substantially higher volume in comparison to the stock pump. But does this mean you can't run an Adrenaline on a stock truck? No way! While its true this pump will deliver the biggest gains on trucks with larger injectors and performance programming, even stock trucks will realize a very noticeable power increase, as well as bump in fuel economy.

NOW STANDARD WITH STAINLESS STEEL REINFORCED THREADS: Unfortunately, the 7.3L's are getting older, and as with most things that get older, parts start wearing out. One cause for concern in relation to your HPOP is that of the threads where the oil lines feed and return. To ensure you don't have to worry about stretching the threads as you tighten down your oil lines, these pumps now feature stainless steel reinforced threads. This pump also now has a 3 year manufactures warranty.

Good Upgrade, I would purchase again
Really not that difficult to install, I bought this because of some of the things I read on forums. Other truck owners recommended it and I did not want to do this job a second time. I Paid for the upgraded stainless steel threads, and I was pleased to see that it came with all gaskets, O rings, and even the O rings for the IPR Valve that I re used. The installation took me and a buddy two hours, a six pack of beer, and 15 minutes to clean up the oil that ran down his driveway. The truck runs smooth and im looking forward to the increased performance. 2000 7.3 Cold Air Intake, 4"" exhaust, DP Tuner, 360,000 Miles and still running strong.

This HPOP has allowed me to take full advantage of my TS 6 chip. It's a noticeable difference when accelerating while towing. It also really smoothed out my idle. My next move is new injectors; I can't wait.

Thanks for the review. You're right, the stock HPOP is the limiting factor on most 7.3L's in gaining the full potential of an aftermarket chip, such as your TS.

Great product and amazing customer service, I originally wanted the terminator hpop but due to longer lead times than expected I switched to the adrenaline pump. They transferred my money from one to the other then I paid the difference. Great quality the truck is more responsive. Will definitely come back for future purchases.

Great product, a little more expensive though!
Replaced the stock pump after it went bad! I think there is a noticeable power gain with this pump! The truck doesn't need to downshift as often while climbing a hill pulling my camper!

Thank you for the review. While the Adrenaline is a great option for replacing a worn out or failed factory HPOP, its a great option to increase the performance and reliability of a 7.3L, as well due to the improvements made to the pump compared to the stock unit.

What is the difference between the 94-95 model year pumps and the 96-03 model year pumps and can they be interchanged??

The 94-95 pumps come with the anti-drainback valve in the pump and use a different gasket. Where the 96-03 have it in the timing cover. They can't be interchanged. Neither one will work proper on the other.


How much is the core charge on the Adrenaline HPOP or is it included in the listed price?

Core charge is added when product is added to the cart. $250.00 core.


Can you replace your stock HPOP with this then attach a swamps gen 3 to it??

Yes, will replace the stock HPOP and function with the Gen3 just the same. SNA


Do you provide return shipping for the core??

No, customer is responsible for the return shipping of the core.


Does the Adrenaline HPOP use the stock quick connectors if you do not get the steel threads? Or does the HPOP without steel threads still use the quick connector stock system? I purchased (CNC Fabrication Replacement HPOP (High Pressure Oil Pump) Lines 99-03 7.3L Ford Powerstroke) lines as well and need to know if they will fit, but I did not get the steel thread upgrade.?

Yes it uses the stock threads, those lines will fit. SA


Will this fit my e99 f350 7.3l with a 15* HPOP??

no it has to be 69* to properly function


Can this pump be used with stock injectors without harm to them??

no you might brake your truck


I have multiple stock high pressure oil pump cores if I sent those in would I be able to get this upgraded pump for cheaper ??
