Fuel Air Separation Systems


#1

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


#2

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.


#4

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


#5

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

Thanks for the input guys.
