I remember thoseI always use a pair of needle nose vice grips to pinch the rubber line before I disconnect the fuel line. This will minimize the mess!! Harbor Freight sells a special plastic pair of pliers just for this job!!

When I pull the fuel line between the sending unit and the hardline?
It's been collapsing on me and I want to replace it...should I expect a shower or a drip?
diymirage...check out my post of Jul. 16 2016 (do search with words....easy fix) about upgrading hose clamps and fuel hoses from regular (R7) to fuel injection hose (R9) and reasoning behind it. I upgraded all the hoses to R9 to head off any possible fuel line problems like you are now experiencing...the aggressive fuels we have today degrade R7 hose pretty quickly. Do it asap before it causes problems in your hard lines and/or carb. Hope this helps you and good luck...318MG
Thanks guys. Do you have any suggestions what to use as a fuel line that will not collapse? Should I use EFI line instead?
So will a pair of honest vice grips, a C clamp.... Crimp the line, either way...Is this a Holley, or AFB/Edelbrock based...?I always use a pair of needle nose vice grips to pinch the rubber line before I disconnect the fuel line.

brilliant...but not applicable hereFor 90° bends in my fuel hoses that go to the carb, I take a piece of 5/16" steel tubing and bend a 90° with a tubing bender, then work it into the fuel hose where I want a 90° bend so the line doesn't pinch/collapse on turns etc... The steel tubing lining the hose will keep it from collapsing... It can take a bit to get the tubing where you want it, but you have to work it a little at a time...

found your post
interesting read

Much much less likely even with a tight bend, which You should obviously avoid. Almost all current SAE 30R9 hose has a teflon liner inside, which is much more resistant tofound your post

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?
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.
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.
Less mess is always the best!! Yeah, I wasn't sure if it was collapsing because the pick-up was getting clogged, or just hose degradation. If the tank was full, and You didit 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
thanks Rusty, ill keep this in mind next time i need a piece (i had picked up a section before you posted this allready)
it barely trickled, like i mentioned, ive spilled more filling up the dirtbikes
