Fuel lines questions
I'm going to try my best and describe the problem. On my way home from hauling my '64 a line came unhooked from the bottom of my truck somewhere and I can't figure out where is it supposed to be hooked up to I am assuming it has to hook up to my gas tank somewhere the other end is hooked up to the exhaust manifold and when i start my truck it has a very good suction but my truck wont run with out gas so i put the end in some gas but not all the way because it sucks too much gas so it just runs on the fumes can anyone help me with this mystery hose ask any questions you have please!!
this is where the line went so i think it had to hook up to something but i cant find it
I took some more pictures

are you sure its the exhaust manifold? i can't think of anything on a '64 (pre-emissions) that would have tied into the exhaust. plus...if it was the exhaust, it would be blowing, not sucking.
are you running an auto transmission? my guess would be the hose to the vacuum modulator on the transmission. but that would be hooked to the intake, not the exhaust.

last time i looked at something like that it was hooked to an old Bendix hydro-vac down on the frame. Follow the brake line from the master cylinder to where ever it goes. If there is a canister about eight inches in diameter and eight inches long that the line goes in to then out of , this is it. The Hydro-vac needs manifold vacuum to provide power brakes.
I have one of these sitting in the garage i took off of a 64 F100, added by a PO to give power brakes without using a booster behind the master.

And probably bent a rod or two if it hydro locked.
Does the brake line go to a tee or to a hydro-vac. I cant see crap in the picture you posted. I will post a picture of one tomorrow after i get home from work.

putting the hose into some gas fumes relieves the lean condition.
but submerging the hose into the gas floods the engine. (and as Garbz said, could also cause hydro-lock).
your best bet (until you can find where it hooks up) is to plug the line. that should get you back on the road. if you suddenly don't have power brakes, then Garbz is likely on the money.
