How much should I expect...

All rubber hoses will collapse/kink if bent tight enough..did you change the old standard hose clamps and upgrade to FI hose clamps also?

it turned out it could rebend the steel lines to avoid bends in the rubber hose altogether
i did forget to buy the EFI clamps, so i used the stock spring type clamps on the inside and then wormgear clamps on the outside

Gates makes EFI rubber fuel hose. O'Reilly carries it. It comes on a light green plastic roll. The hose on the black roll is regular carbureted hose.

thanks Rusty, ill keep this in mind next time i need a piece (i had picked up a section before you posted this allready)

Oh, to actually address the original question, it depends on how much fuel is in the tank. If You remove the fuel cap(very important!!) & have the line pinched, You can blow
thru the line back into the tank as you un-pinch the hose, this will break any siphon effect. If you don't remove the cap, even w/a clear vent, it will be dry for about .4secs.,
then you will be getting a petrol facial!!! If the level is high, well, plan to drain it or work on it whilst it's trickling steadily.

it barely trickled, like i mentioned, ive spilled more filling up the dirtbikes
