How much should I expect...

found out when you pull that line it is barely a trickle
ive spilled more then that filling up the lawnmower...but then again, i dont usually do that laying on my back

For 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...
brilliant...but not applicable here
well, not completely, i went and grabbed a junk piece of 5/16th fuel line i had downstairs, spend 45 minutes looking for my tubing bender
then i got under there and found out the main issue was a misalignment of the hard line and the sending unit

so time well wasted, i got to use my tubing bender (remember, the one i spend 45 minutes looking for) to align the hardline with the sending unit, and now there is a less then an inch gap that the R9 covers

So will a pair of honest vice grips, a C clamp.... Crimp the line, either way...Is this a Holley, or AFB/Edelbrock based...?

not sure if this was directed to me or gill, but i was working on the tail end of a duster, which has a proform 750 up front, basically a holley double pumper
