Fass Fuel Systems

Fuel Air Separation

Fass fuel systems

The goal of fuel air separation is to keep contaminants from hindering your truck’s performance. One of the main reasons for this is due to how diesel engines operate. Vehicles with a heavy amount of responsibility require fuel air separation in order to maintain activity. The engine is tasked with producing power and torque on a continual basis. When the system has to constantly work at a high level, it is exposed to more risk such as air or and/or dirt reaching the system. With adequate fuel air separation, risk is greatly reduced. Fass offers a variety of replacement diesel pumps meant for this application.

Without using fuel air separation in your truck, air, moisture, and dirt can play a factor. Strain can be put on the system to distribute diesel to the engine. Air in the fuel line affects the injectors, causing the tips to function erratically or break down. If this occurs, the pistons are also in danger. You may even notice other common symptoms such as weaker horsepower, rough idling, and of course, less fuel mileage. It will be a matter of time before you need a replacement diesel pump. Changing out the original unit with the same design will lead to similar issues. A Fass diesel pump provides a much greater amount of efficiency than a stock part. It will last longer, too.

One of the first benefits you will notice from going with a Fass diesel pump is improved pressure. There will be a quicker throttle reaction, as the fuel system will not be forced to pull compromised energy through the line. You will also see a rise in horsepower with a Fass diesel pump. It will not be a very high increase, but being that your engine is no longer being fed dirty fuel that bogs down the system, horsepower potential is more available. The biggest improvement most report is in fuel economy. Depending on truck model, a replacement diesel pump from Fass can offer an increase up to 12% in MPG.

There are several options for you to choose from. Fass diesel fuel filters are made for Duramax, Cummins, and Powerstroke engines. Select based on both your engine configuration, model year, and needs. Some replacement diesel pumps come with an optional heater port to protect against cold weather starts.
