Additional Information About FASS Fuel Pumps

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, 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 kit.

The FASS Fuel System was designed to give yesterday and today's diesel engine "Test Cell Performance" in "Real World Conditions."

Recognizing the conditions of the test cell vs. real world application introduces a whole gamete of variables affecting the fuel supply/delivery to the engine;

In a manufactures 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
