Time to drain gas from the tanks and carbs.

…only get the kind that stops flow instantly, from both ends, when disconnected.
a second QD, attached to a length of fuel line, makes draining simple.
I even run one on my remote, IV-like tank, used for maintenance .

I use the same QD system on my remote/maintenance tank.
Disconnect the female side, last photo, plug it into the bike’s QD and drain away.

i decided to dig my bonanza out of its cocoon in the corner of the garage its been about 3 years since iv ridden it and i know it had about 1/3 of a tank when i put it away last. any how the gas smelt okay and started and ran fine so i ripped it around the neighborhood till it ran out of gas refilled the tank and moved it to its new more accessible storage spot... thats my winterizing process i guess lol
