Fuel Air Separation Systems


What do fuel air separation systems like Fass Fuel do for diesel vehicles? Is it recommended to install one on diesel engines?


Looking that link over, it seems to me that it’s just a fuel filter brand. Most diesel engines would already use a system of sorts. One filter/water separator, then a second filter before reaching the injectors.


Its to remove air bubbles from the fuel, I don’t think its necessary, but I do know that air bubbles in a diesel engine can cause them to stall out or otherwise run like crap.


Unless you’ve got a problem with the fuel system however, you shouldn’t have to worry about air bubbles.


The only time I saw that problem was due to fuel starvation


Thanks for the input guys.
