Z400 Gas tank...

[z400hick85]

Does anyone happen to know how to drain the gas tanks on these quads? It looks like the petcock is directly bolted to the tank and I don't wanna go through the hassle of taking the tank off.

unhook the fuel line from the carb and turn the gas on. it wil all drain out. thats how we do it. we dont have a z400 though. im just guessin it will work.

or, if there is a fuel filter, unhook the fuel line from one side of it instead of the carb.

Pull the fuel line off the carb and turn the petcock to prime. It won't empty the whole tank but it will get most of it out.
