HI all, today I mixed my 50 gallons of kero, as I do each year. This time I bought a 10 micron filter and pump.
The first thing I noticed, after I set up the system with the filter on the suction side, I could never stop the air bubbles, so I put the filter downstream of the pump, and worked great.After the first 15 gallons went through, I thought I should add another small filter on the suction side, a new pump and all, did not want to wreck a new pump. Well guess what, air bubbles again, and no matter what you did to the oriantation of the small filter, their was air bubbles.
Conclusion, Jetcat and Jet Central say install the fuel filter , down stream of the pump, they are right, never install a filter on the suction side, the filter ,actually separates the air from the fuel.
I also noticed the static electricity formed at the filter. look at the second pic of the hair on my arm, and then when I move my arm close to the filter, see the hair stand up.
