FASS PUMP INFORMATION

We have some very exciting new about the warranty accompanying the FASS Product line. The FASS warranty is now the same for Bio-Diesel/ WASTE VEGETABLE OIL fuels as it is for diesel fuel. 


General Info About FASS Fuel Pumps and Accessories

The FASS Fuel Air Separation System provides the most effective technology designed specifically for diesel engines to remove water, particulates, vapor and entrained air from diesel fuel. The FASS Pump System replaces the Cummins factory lift pump and filters system, and enhances the fuel delivery to the Powerstroke and Duramax with a commercial duty system designed to last between 13,000 to 15,000 hours of continuous use. FASS Systems are covered by a lifetime warranty on select models.

Your High Performance diesel engine demands higher fuel flows. Yet, higher fuel flows increase the vacuum at the fuel pump and agitation in the fuel tank. These factors generate additional air/vapor in the fuel system preventing your engine from producing maximum power and efficiency. Incorporating the FASS Fuel Pump System into your diesel engines fuel delivery system will remove the entrained air/vapor which has been proven to cause galling and pitting of the injector barrel and plunger assemblies. The FASS Fuel Pump System is the best possible insurance for helping to prevent injector tip erosion.

Most vehicles fuel tanks are mounted at least two feet below and ten feet away from the fuel pump. This configuration creates multiple problems associated with the fuel delivery to the engine. First, the injection pump has to draw the fuel from the tank by creating a vacuum which produces fuel vapor. Second, while the vehicle is in motion the movement of the fuel inside the tank causes air to become entrained within the fuel. FASS Fuel PumpsBy having entrained air and air vapor in the fuel, the engine does not perform at the manufacturer's specification, and the fuel injectors and fuel injection pump are not properly lubricated. Air and fuel vapor occupy the space that should have pure fuel, thus delaying the injection of fuel (retarded timing) into the combustion chamber. The air/vapor present in fuel is very inconsistent, making it virtually impossible to adapt the varying degrees of changes in injection timing.

The answer to this problem is the FASS Fuel Pumps.

Recognizing the conditions of the test cell vs. real world application introduces a whole set of variables affecting the fuel supply/delivery to the engine. In a manufacturers test cell, if you ever have the chance to go on a tour, you will recognize optimal engine conditions. Optimal engine conditions equal optimal engine performance. Optimal engine performance consists of optimal fuel supply. Manufactures' tests vary slightly from one manufacture to the other but are configured with these basics:

  • Fuel tank is usually at least 10 feet above the engine
  • Fuel tank is stationary
  • Return fuel is returned to a separate tank

With the optimal fuel supply achieved, the fuel injection system can perform the job for which it was designed, keywords, optimal performance. That is to deliver virtually pure fuel to the injectors at the proper pressure; the injectors can then deliver the proper amount of fuel at the proper time into the cylinder for a more complete combustion. Understand fuel injection systems were designed to inject a predetermined amount of fuel at a predetermined time.

Give thought to the real world applications. As you might have noticed, we are unable to raise our fuel tanks higher than they are.

  • Fuel tanks are usually below the engine and separated from the engine by 5 – 15 feet
  • Vehicles are in motion
  • Hot return fuel is routed into the fuel supply tank

HOW FASS FUEL PUMPS WORK
FASS Fuel Pumps


Huge corporations and schools from around the world recognize that entrained air/vapor in fuel as a problem. We've listed only some of the symptoms air/vapor has on engines to help you better understand how serious the affects can be. You will be able to see these topics discussed throughout our documentation. Other factors can create these same symptoms however; we do know that air/vapor will cause these symptoms:

  • Inconsistent Flow Of Fuel
  • Low Horsepower
  • Loss of Power
  • Sluggish Feel
  • Low Fuel Mileage/Poor Fuel Mileage
  • Entrained Air Wastes Fuel – using more fuel to achieve the same results
  • Excessive Smoke
  • Injector Failure
  • Harm to the Injection System Components
  • Hard Start or Will Not Start
  • Engine Surges at Low Idle
  • Warm Engine Runs Rough or Misfires in Operating Range
  • Rough Idle
  • Engine Will Not Reach Rated Speed When Loaded

About the Company Behind FASS Fuel Pumps

The FASS product line is protected by 2 patents, 7,025,048 and 6,892,710. The company became incorporated in April of 2003 and started in a garage selling 30-40 units per month. The company now has grown to about 1,300 units per month and prides itself on the excellence of the product as well as the reputation of the company. The FASS products were invented by Brad Ekstam, president of Diesel Performance Products, Inc. Brad knew there was a problem with a diesel engine’s performance. Through many tests and discoveries the FASS product line was born.

As the product grew in demand, there were more opportunities to discover the full potential of our product. Through countless hours of research and development, the company has improved its products to be the best of their kind in a growing industry. The Fuel Air Separation System, known as the FASS, and the High Performance Fuel Pumps, known as the HPFP, have had the privilege to be part of some of America’s favorite racing, pulling and off-road teams! The company manufactures and assembles the products entirely in the United States. The company is members of the Specialty Equipment Market Association (SEMA) and attends the shows regularly.

In the company's own words:

"We, at Diesel Performance Products, have over 15 years experience in building the highest quality Fuel Air Separation Systems and electric diesel fuel pumps available. It is this experience that has lead us to use a gerotor specific fuel pump. Our success in the class 8 truck market has been above the rest. Our pumps typically last around 500,000 + miles! Since 1994 we’ve made many improvements to increase life expectancy and dependability. Our confidence is evident in our warranty. We started off with a 1 year warranty and we now offer up to a conditional 6 year warranty!!

In 2003 we not only set the standard for diesel fuel pumps in the pickup truck market, we “KEEP” raising the bar. With over 90% of our machining, and all of our assembly and testing performed under one roof, we maintain the highest quality standards throughout the industry. The FASS Systems undergo 25 vigorous tests before being shipped. Both designs are subjected to numerous tests for your quality assurance and to maintain the highest standards.

Our R & D department is continually improving the FASS product line. We realize the design of the FASS product line exceeds performance and quality expectations. To create this standard, we use one of the highest grades of aluminum, T6061, as a major component. As you may already know, we also use motor specific brushes in our electric motors to maintain the same high quality standard and increase the overall life of our units. Due to the brute size of our motor armatures we are able to achieve superior levels of stall torque. The increased amount of stall torque insures extreme cold weather starts by flowing gelling fuel."

Note: It is recommended that you do not run a FASS pump with a higher gallon per hour rating than your engines present Horsepower output. There is a great potential to decrease the life expectancy of the FASS fuel pump. The higher the GPH rating on the FASS pump the greater the noise output will be.
