    New upgrades to the CPR  include new B-100 Bio-Diesel Compatible components.  The Seals in the filter are B-50 compatible. All of our systems are Ultra Low Sulfur Fuel compatible (ULSF)


    There's no denying that a proper fuel system can make the difference between a good running truck and a GREAT running truck.  Even if your truck is still stock there are benefits to installing a proper fuel system.  Although it provides power enhancement, the added longevity to your OEM or aftermarket parts is the key concern. The DIESELSITE CPR Fuel SystemsTM address this concern and provide protection for your fuel system parts.  This protection applies to your factory fuel pump and injectors for the stock truck and any aftermarket pump or injectors for those who have replaced them.

    The CPR Fuel SystemsTM aren't just about power and longevity.  We've provided a bolt in solution to make installation easy for any level of mechanic.  The hardest part of changing your system will be lowering your fuel tank for the pickup and return modifications.  In fact, if you have even a fair level of mechanical ability you should be able to install the entire system in about 8 hours.   

    We've been diagnosing and building Ford 7.3L Powerstroke fuel systems since 2001. We created the 1st fuel systems ever for the Powerstroke. Our systems have been created to correct issues in the 7.3L Powerstroke fuel system.   We've added ease to the maintenance of your fuel filters and given you the ability to see problems within your system with a clear bowl in our pre-filter.

    These systems are all about longevity for your parts by providing removal of dirt, air and water.  But, an added bonus is the power enhancement to your existing upgrades that you can expect after replacing your fuel system… Every performance upgrade that you can add to your truck will be maximized. .  By providing good quality and sufficient quantity of fuel delivery to your injection system, you'll see peak performance from every performance upgrade that you install. Give your injectors the amount of fuel they need or your chip the amount of fuel it asks for and you'll be seeing more effective results and power gains than you can realize with those parts alone.  Improve the “heart” of the system and you'll improve the end results.

    Our Complete Pre-filtered Regulated Fuel System…

    There is no other fuel system like this one on the market for your 7.3L Powerstroke.  Extensive testing has gone into the design of this fuel system. Years of diagnosing problems seen with OEM or other fuel systems has given us the data, research and development opportunities to make sure that this system works.  PERIOD.   It's not just a bunch of parts slapped together, put in a box and sold as a miracle cure for what ails your truck.  When we began developing these fuel systems almost four years ago, we tested several designs.  We are comfortable with only one - and it's the only one we'll put our name on.  A complete system to address all issues at once.  We found that adding components a few at a time can sometimes cause as many issues as they are attempting to address.  This is why we will not break the system up into modules you can add one at a time.  We know what works and that's what we've built for you.  A complete pre-filtered and regulated powerstroke replacement fuel system. There is no way to guarantee you the result that we know our fuel systems deliver without every piece of the puzzle in place.  We've got the safest, most complete and easiest to install fuel system replacement you'll find.  From the pickup in the tank and back to the return, we have addressed every problem with the factory fuel system that we had issues with.

    Here's what you get…

    • SIMPLIFIED PICKUP IN THE TANK: Simplified pickup using 100% NITROL hose, stainless tubing and solid stainless clamps (including the screws) in the tank for years of trouble-free service. *The tank is where most air problems occur.  From the beginning, our changes in the tank have given customers relief from air issues that start in their tank. It's simple, it works. PERIOD.
    • PRE-PUMP 2-MICRON FUEL FILTER/WATER SEPARATOR: A 2 micron pre-pump filter to remove large particulates and water. For quality control all pre-filters will now be a Dieselsite/Dahl fuel filter water separator.  You will have superior water separation and equal or better micron rating than the factory fuel filter ever provided!

    • REPLACEMENT FUEL LINES TO PUMP: Replacement of entire supply line from the connection at the top of the tank to the OEM or aftermarket pump with bio-diesel rated fuel hose. 
    • REPLACEMENT FUEL LINES AT HEADS: In all of our CPR Fuel Systems, we use a method that is unlike any other we have seen on the market.  Our system places your regulator in a position that allows for maximum fuel FLOW to all injectors and an even and consistent fuel pressure throughout the system. This is the meat and bones of why ours is 100% self purging and provides consistent even pressure - especially in the heads - for longevity of your injectors. call for more details...
      A “DIESEL RATED” REGULATOR FROM AEROMOTIVE - CNC machined from 6061-T651 billet aluminum alloy with stainless steel hardware. It is finished with a “bullet Proof” hard-coat anodized exterior. Only the diesel rated regulators are warranted for use in diesel applications. 
    • A custom fitting on the OEM filter housing - CNC machined from billet aluminum. This is a unique item found only in the Dieselsite CPR fuel systems. This fitting allows for the removal of the OEM regulator from service while providing a connection to the OEM return line with no cutting or modifications. This makes a very clean and easy installation. The factory regulator is inadequate.  It does not provide adjustability or the location that is needed(end of the line before returning to tank).  We do not want it in our systems.  We want only ONE controlling factor on the pressure in the system - the Aeromotive Adjustable Regulator.
    • Swivel connections at the ends of all hoses, push lock and o-ring fittings are used for easy installation. 
    • Two check valves - The first is IN the filter. The DIESELSITE Dahl Fuel Filter/Water Separator has a check valve built in. This is the only check valve we have ever used. With the introduction of the CPR Fuel Systems we have added the second for protection from drainback during your filter maintenance. The second is only needed during filter maintance and is there for your convenience.  As our system is 100% self-purging, you won't have a concern if you cycle the key a few times before starting.  However, by eliminating drainback, your system will start just as easily and quickly as it did before your fuel system installation.  There are no cold start issues with the CPR Fuel Systems.
    • Complete bolt-on setup - pre-mounted on custom brackets for the pre-filter, regulator, and the return line cooler.
    • Pushlock fittings and swivel connections for easy installation (also easy removal and replacement should any issue occur) 
    • We have added return line fuel cooler unit that will remove most of the heat picked up by the heads. Cooler fuel, denser fuel, better efficiency, better power and longer pump life will be realized with this addition to your fuel system. With the heat picked up by the heads, even in the winter, gelling issues are not a concern.
