Hi gaRCfield,

I have two lines sticking out of the firewall of an almost completed Ultra Sport 60. Since I ran those lines last December, I have no idea which is the fuel pick up line and which is the pressure line.

I'll try to figure it out before the first flight!

I think I'll fill the tank half way, then stand the model on it's tail and try to de-fuel through one line. If I can get fuel out, then that is the pick up line as the clunk is at the bottom of the tank and will have fuel to pump.

If I get nothing but air, then that line must be the the vent/pressure line and I'll proceed accordingly.

Clear as mud, eh?
