I don't know if this is the proper place for this, but here goes..


I have ordered an '04 Silverado Duramax, and am currently researching what to do to best protect my investment. I have been thinking about getting a Racor kit from Greg @ Lubespecialist, and installing an AC Delco lift pump to aid fuel supply. Then, in my searching and reading, I discovered the FASS and Preporator.


Now I'm really confused... Would the Lift pump/Racor filter be plenty for 98% of us out there? Broker has had more than one Duramax at or beyond the 500k mark, and I would guess he's probably not using the FASS or Preporator.


Should I get the Racor kit and lift pump and be happy, or save up and get either the FASS or Preporator?


Thanks,


Dave

I'm going with the Racor and Pump, although I'm sure you could skip the pump, if your not planning on adding too much HP. I'm sure both the Fass and Preporator would also work well> I don't believe that air is of much concern, and can't justify the complicated install, and cost.

The fuel injection system on the Duramax is a common rail system. Injection timing lag caused by the presence of air/vapor in the fuel is not a big factor, if a factor at all. However, several points should be considered when spending your hard earned $$$ to upgrade your fuel supply system.


First point: All pumps operating under a vacuum or actually even a positive pressure flow insufficient to meet the demand of the pump can cavitate and produce vapor. Additionally, air becomes entrained in fuel by the mechanical action of sloshing in the tank. This condition can quite possibly reduce the mass flow of the pump and result in lower than designed rail pressures and poor performance.


Second point: Bubbles in the fuel implode when subjected to sudden and severe pressure changes such as those experienced in a fuel injection system. When these bubbles are next to the wall of the injector barrel pitting can take place which may eventually lead to lower pressures and poor performance, also component failure.


Third Point: When the bubbles pass through the tip or nozzle, tip erosion can occur as well as poor spray patterns. This also results in poor performance.


So, what to do, go with a standard system (plain old pump and filter), or a system (fass) that advertised 3,500 current customers and then admitted in state court that the 3,500 current customers were actually Fuel Preporator customers. Also admitted in state court action, the fass had been designed by altering the blue prints to the Fuel Preporator (old style system. In fact, the fass uses 17 identical and interchangable parts of the old style Preporator). Did you know that the manufacturer of the fass is currently in Federal Court answering Federal Patent Infringement charges! Wouldn't you rather go with the Original Air/Fuel Separation and Delivery system with additional new technology, the Fuel Preporator.


New Compact Fuel Preporator FP-80 AIR DOG and FP-80 hp has relay controlled wiring harness, fuel flow pressure and filter changes monitored with pressure switch and dash mounted indicator light,water separator and 6 micron StrataPore tm filtration, mounting brackets, fuel fittings and fuel lines.


The Fuel Preporator (trademark is registered) is ISO-9001 Quality Manfactured, approved for sale and use in California by CARB, Tested by: University of West Virginia Engine and Emission Lab and found to improve performance and emissions, University of Illinois and found to remove air/vapor from fuel, Milwaukee School of Engineering for water removal, recipient of $1,750,000.00 in federal funding for military testing and patented in the United States with PCT patent filings in 117 countries.


Don't you really want the best for your truck? Why settle for anything less????

Thou doth protest too much.


I went with the Fass. Might be a mistake but only time will tell.
