RE: Fuel Filter Orientation, does it matter ??
RCISFUN
I have mounted the UAT in various positions. I spoke with Bob (BVM) and asked him to check my UAT install. He did and told me the orientation as long as it was not upside down did not matter. I am currently flying with one horizontal.
Fuel filter. Our fuel filters supplied have a directional arrow for fuel flow. I never mount them anyway but horizontal and always back near the turbine for easy access and maintenance.
Fuel solenoid: I do not recommend removal for one primary reason. . .safety.! This as most all know, shuts fuel off instantly to the turbine.
On any new install, I enlist the help of others, run the jet and hold it in various positions while shaking. Prior to this, I pump fuel through the pump into a catch can until I am sure all visible bubbles are gone.
Hope this helps. . .
