FASS Fuel Systems


FASS-150 series shown above
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. By having entrained air and air vapor in the fuel, the engine does not perform at the manufacturer's specification. 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 kit.

Features: Fuel Pump, 10-Micron Filtration, Water Separator, Includes Fuel Heater
Real World Conditions - In the real world, the fuel tanks are usually mounted at least two (2) feet below and ten (10) 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. When diesel fuel is drawn by a vacuum fuel vapor is produced. Second, while the vehicle is underway the fuel is sloshing around in the fuel tanks creating entrained air. This circumstance has created a situation far from the test cell conditions which results in air and vapor being mixed in with the fuel when it is delivered to the injector. By having entrained air and air vapor in the fuel the engine does not perform at the engine manufacturer's specification. Air and fuel vapor occupy the space that should have pure fuel, thus delaying the injection of fuel into the combustion chamber. This phenomenon is better known as "RETARDED TIMING." The air/vapor present in fuel is very inconsistent making it virtually impossible to adapt the varying degrees of changes in injection timing. The retarded injections cause a multitude of problems in the combustion chamber!

FASS Pre-Filter Notice
When the water separator of the FASS Fuel System or the strainer for the HPFP's is replaced, make sure to replace it with an element consisting of a 144 micron wire mesh material. We use a stainless steel wire mesh element to pre-filter, resulting with much less restriction than a paper element.

We are finding many technical calls relating to restriction issues cause by the use of improper materials on the suctions side.


Lifetime Warranty
FASS is pleased to share with you the same confidence that we have in our product. That is to say, when you buy a FASS or HPFP we are so sure that it is the best quality you can buy that we’re going to give you a LIFETIME WARRANTY (on selected part numbers). On your select model of FASS and HPFP, you can drive off with that feeling of security.

New FASS system draw tube location - Note from FASS
Before installing any of the FASS Systems or the HPFP’s that require the draw tube to be installed from the kit, please refer to the instructions. We now have a better location to mount the draw tube, which will allow there to be more usable fuel before running empty.

In the kits that will allow the move to this better location we have put a longer bulk head fitting in the kit. This will give the draw tube the available length to reach the bottom of the tank. Please follow the instructions accompanying the kit. If you try this new location with the wrong combination bulk head fitting and draw tube you may come up short.

I have performed this on my personal truck; it works great especially when the truck is low on fuel and you are on a step incline.

Have a great day!

“Setting the Standards”

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.
