Cylinder UATs - why is the fill on the bottom?
I’ve always been a BVM/Hanson/Kingtech UAT user for no real reason in particular, just came into jets always using that style. On a current project I opted to try a Digitech, which really I have no complaints about with the exception of the fill port being at the 6 o’clock position on the face of the tank. So what I’m finding in contrast to my BVMs is it’s pretty dang hard while filling to get that last bit of air out of the top, but worse than that is if I don’t act quickly to disconnect my fill line after shutting off the pump it starts siphoning the fuel right back out of the bottom of the UAT. The model sits pretty tall and thus the UAT is higher than my pump station when set on the ground, nevermind the fact that I sometimes fuel my jets while on a stand or a table with the fuel jug on the ground. Obviously I could elevate the pump/can when fueling to prevent this, but I also thought about just rotating the UAT cylinder 180 degrees in its mounts to have the fill at the top, which would hopefully prevent this. Am I the only one that has this issue? Am I overthinking it?
