FAQ:

Q. Is a complete system really necessary?

A. Ask the hundreds of people currently running our systems and I'm sure you'll get a big YES. Better yet, ask those who came to us for help in "fixing" a bad purchase. Most people think that just adding a regulated return is the answer to fuel system upgrades. Our system IS a regulated return, but it includes all the tank modifications, the pre-pump filter, the return line cooler, the regulator, and all the new fuel delivery lines. This is the only way to correct your fuel system problems without introducing even more.  It was designed for ALL LEVELS of powerstroke needs. From the stock truck to the highest HP. We have a system for everyone. DIESELSITE does not sell you sections of a fuel system that you have to add up to see your real cost. You get a 100% complete, tested, Bio-Diesel compatible system. We were the 1st to meet this rating, the only to offer a fuel cooler, and still the only to offer the proper filtration required for a regulated return system. All this and the CPR is still competively priced with much simpler, less equipped systems. There is still no comparison.

 

Q. Why don't you offer an option to delete your fuel bowl?

A. WE DO!  Our CPRx and our OBS CPR Fuel systems both eliminate your fuel bowl.  In fact, our 1999.5 PSD was the FIRST fuel bowl delete.  We removed our bowl and everyone thought we were crazy back then - it's interesting how much other fuel systems resemble ours now though. How flattering... We've been using return line coolers for years and you'll notice that every brand of light duty diesel now comes with a fuel cooler.  ;-)  We're filtration experts and we inform our customers that the volume a regulated return pushes through that fuel bowl are not what that filter was intended for.  So, it's filtration properties are greatly reduced due to the increased volume and no longer sufficient for primary filtration. However it's still a very good secondary filter at the higher micron rating.  It IS extra protection for your injectors should your fuel pump ever fail.  (CPRx and OBS systems which are fuel bowl delete systems by design have post pump filtration included as does the option for removing the fuel bowl in our CPR/CPRx systems). The Dahl is 2 micron and designed for these flow rates. That becomes your primary filter.  Removal of the fuel bowl is only necessary to make room for something else under the hood, or if your fuel bowl is broken and you don't want to replace it.  It's a personal preference. Sure, it's nice to make room for other things under the hood, and the fuel bowl delete will do this - but, it isn't necessary to remove that filtration that your OEM filter still provides. 

 
Q. Is your system complete?

A. Yes. Most people think that just adding a regulated return is the answer to fuel system upgrades. Our system IS a regulated return, but it includes all the tank modifications, the pre-pump filter, the return line cooler, the regulator, and all the new fuel delivery lines. This is the desired way to correct your fuel system problems and was designed for ALL LEVELS of powerstroke needs. From the stock truck to the highest HP. We have a system for everyone. We at DIESELSITE do not sell you sections of a fuel system that you have to add up to see your real cost. You get a 100% complete, tested, Bio-Diesel compatable system. We were the 1st to meet this rating, the only to offer a fuel cooler, and still the only to offer the proper filtration required for a regulated return system. All this and the CPR is still competively priced with much simpler, less equipped systems. There is still no comparison.

Q. Do your systems work with aftermarket High Pressure Oil Pumps (HPOP) or turbos?

A. Yes. All the CPR systems will work with all aftermarket oil pumps and turbos on the market. No need to order a specific system to fit your application.

 -----------------------------------------

Q. Does the Aeromotive 2 year marine warranty cover use in the truck application?

A. Yes. It is covered for 2 years in ANY diesel application. Any of this information can be verified by calling Aeromotive tech at 913-647-7300.

-----------------------------------------

Q. Is there a difference in the Red and Black (Marine) Aeromotive lines?

A. Yes. While there are small internal differences, the external coating is a hard coat anodize. This makes the finish resistant to diesel fuel and alcohol. The most important difference is the warranty. The red line carries a 1 year warranty for gas applications only. The black (Marine) line carries a 2 year warranty in any application including diesel. Again, any of this information can be verified by calling Aeromotive tech at 913-647-7300.

-----------------------------------------

Q. I recently read about an Aeromotive pump failure on a diesel truck. Have you seen this or have any information about this?

A. To date, we have had no failures on any Aeromotive pump in any of our CPR"e; Fuel Systems since we started using them in 2001. We are an Aeromotive distributor and supply many other companies as well. We did have 3 pumps that had leaky terminal seals. This was resolved quickly and affected only those few trucks and no failure was involved. It was just a leak and was obviously a bad run of orings or some similiar manufacturing glitch which was caught very quickly. Those customer's pumps were repaired immediately. This was many months ago. The issue never resurfaced. The Dieselsite CPR Fuel System was built while in constant communication with Aeromotive Tech and to date we have never seen a failure of any pump or regulator. Any of this information can be verified by calling Aeromotive tech at 913-647-7300.

------------------------------------------

Q. Do I need a speed pump controller for my pump to protect the life of it?

A. No. The design of our systems negate the need for one. They are primarily used on non-return (dead-head) systems.

------------------------------------------

Q. Can I run an air separator system in conjunction with your kit?

A. The addition of these units will not negatively effect the CPR or any of its components. They should be installed between the tank and the CPR pre-filter. Our pre-filters are made to handle up to 25 psi pressure. Most of these filter air separator units supply about 14-15 psi.

-------------------------------------------

Q. Why do we need a fuel cooler?

A. The OEM system does not return hot fuel to the tank. Hot fuel is returned to the inlet of the system to be re-used. Therefore the fuel tanks are dsigned to hold heat in (insulated material) to keep the fuel from gelling in the winter. A return system, as in the CPR systems, return the hot fuel to the tank. We use a fuel cooler to bring the temperatures down to an acceptable level before they enter the tank. This way, the pump and injectors get a consistant cool fuel charge. Note: The cooler on the CPRx is much larger than on the CPR due to increased flow rates.

--------------------------------------------

Q. Why do we need a pre-filter?

A. Short version: Fuel delivered THROUGH the OEM fuel filter in stock form is about 4-6 gph, while with that same pump and the same delivery rates, the fuel delivered through the OEM fuel filter with a CPR (or any return system for that matter) is about 24 gph. This rate is far above the tested rates the filter manufacturers ever intended them to see. They do NOT separate water to any degree, nor do they filter particulates to any degree that they were designed to. Basically, the OEM filter is just a simple secondary filter at this point should something in the pump come apart. It is not protecting the injectors from small wear particles.If your system uses a basic "e;spin-on"e; style filter -- your gambling with expensive components. No "e;spin-on"e; filter will properly protect you, nor will the lone OEM filter.

--------------------------------------------

Q. Why do we need such a large pre-filter?

A. With the special needs of a PSD return type fuel system, we found only ONE filter on the market designed to handle the flow rates we demanded while filtering to OEM requirements. In fact, the pre-filter in our CPR is rated for twice the flow rates we are pumping, while doing so at 2 microns. This is protecting the injectors AND the pump, which had no filtration protection in the OEM design.

-----------------------------------------

Q. What other benefits may I see other than good fuel pressure?

A. Smoother Idle, smoother acceleration, quieter operation, better fuel economy, longer injector life, more horsepower, and the one that the CPR alone can offer..... complete and instant air purge of the fuel lines and rails. No other system, including stock can completely purge the rails of air this fast. This comes in real handy should you run out of fuel, or simply if your changing injectors, fuel filter, or such. With just a simply cycle of the key once or twice, the system is full of fuel and the air is removed to the atmosphere.

-----------------------------------------

Q. I've heard of some systems having slow starting issues. Does this apply to yours as well?

A. No, we know why others have had this problem. We created the solution in the CPR before it ever went to market. We still to this day have this in place, and have engine starts just as fast if not faster than stock, hot or cold.

-----------------------------------------

Q. I live in a cold climate. Do I still need to hook up the fuel cooler?

A. Yes, you need to hook up the cooler. The new routing of a return style system picks up much more heat from the engine than the original returnless style OEM system. The fuel will never be too cool reguardless of the climate. The factory tanks on the superduties are plastic and don't give up much heat.
