On gas /glow do you use the same tank and fuel lines as for glow? I assume that the fueling pump must be for gas.

The fuel tank, lines, and any pump you use must be "Gasoline compatible". The hobby shops sell gasoline pumps, and conversion kits for the fuel tank. The stopper in the fuel tank must be changed, and the kit includes the stopper.

Here's a thread with info on fuel lines: http://www.rcuniverse.com/forum/m_6026041/tm.htm

Thamk you for the info. I have a Poulan 25 cc ready for a run

I like Hayes fuel tanks with the black neoprene fuel line. Fully gasoline compatible & no stopper to back out.
