But some time if I dont putch the screw to the end in this fill line and the UAT was getting air thru that fill line. So be carfull when filling your gas tank.[:-]
Good luck

Exactly, we had a guy flame out the other day his main tanks were almost full, but UAT amlost empty. You have GOT to make sure the fill line and all connections on the fill line do not leak of you will drain the UAT and not the mains. I have seen that screw in the fill line trick, I do not like it, nor that simple plug. I like a good high quality (non festo) petcock.

Mr. Matt - great idea! I like the idea of the petcock valve...the plugs get loose over time, especially the medium yellow Tygon tubing. Thanks!

I think it's an IM/Tetra part but have only seen it at the Jet-Cat site. Central Hobbies may also carry it.

one more thing to add....you can use a festo check valve for any engine under 20 lbs ....simply insert your fill line and fill.....but dont use it over 20 lbs or the turbine suction will open up the check valve and suck air too.......i use a plug and a festo cock valve and never deviate....and never flame
