the top of the tank is 5-10mm (1/4-3/8") above the level of the
needle valve. A 1/16" wire (not included) can be used to extend the
needle valve by inserting the wire into the pre-drilled hole on the

screw. Remote needle valve is held in place by a nut instead of
screws. To use a Tru Turn spinner and an APC propeller, modeler will
need the Tru Turn jam nut set TT-0378-A (not carried at this time).
