Gary,

I put the PST air trap in the FEJ 1:5.5 scale F-16 yesterday. It fit in the same spot as the Hansen air trap. Just had to change the Tygon lines over and that was it. The bottle is setting on its side with a slight upward tilt. When I put fuel in the plane, I held the nose up so most of the air escaped the bottle. Then I tested the system with the GSU up to 6 volts. No problem. This things works just like a header tank. Very little resistance to flow.

When taking the fuel out, some air gets into the bottle but the white filter material is still fully submerged. I think I will try running it this way. I see no reason it has to be mounted vertically. Although, if it were, all the air could be removed during fueling. The only downside I can see is that you can't get all the air out of the bottle when it is mounted on its side.

Oh, and I love the pink cap! I think this is going to work out great.

I used 1/8 th Tygon from the bottle over to the pump. Was a liitle tough getting the line over the large nipple on the bottle. But no problem on the Jetcat pump. 1/8th Tygon fits perfectly on the pump nipple. I know you like to use 6 mm clear tubing. I tried some on the bottle nipple. I couldn't get it to push on. You might have to go to 8 mm tubing. It is that big. Let me know how you end up plumbing yours.
