What diameter and length tube should I purchase to siphon gas from one bike to another?
Auto Zone sells an inexpensive gas siphon kit. The "full" tank motorcycle will have to be higher than the "empty" tank motorcycle for a siphon to work (gravity). Bike to bike transfer, if both are at the same level, would require a pump.

My guess is that 3/8" ID tubing that you can get at Lowes or Home Depot would work. But you can just measure the OD of the pump nozzle the next time your at the gas station to be sure.

Hi TXCHOP: Thanks for the link, that product looks great. Regardless of how much gas costs, when you are in the middle of nowhere and run dry, a siphon tube is much better than walking or riding bitch on the back of your buddies bike.
