The petcock is not vacuum activated, note it only flows by gravity if the tank is over half full that's why there is a fuel pump on GL's. The switch itself can be taken apart..but you have to drill out the rivets and to get it back together use small nuts and bolts..the older petcocks from the 1000's were built that way new rivets!!! You can buy rebuilt kits for them..basically two 0 rings and a larger 4 hole gasket. The lever has a crescent shaped groove and as you turn it it opens different channels reserve, regular and closed. Your tubes in the tank maybe be clogged or the screens that protect them,,look in the tank by removing the sender gauge..

Test the petcock 1st if you want by filling the tank, take the bottom tube off the petcock at the fuel pump and put it in a jar open the petcock fuel should flow in either position and stop when closed..

To test the pump hook the line back up..take off the other line at the pump attache a temporary line put it in a jar and crank the engine..with the stop switch on ..OFF..or...on the engine shoudl run for quite a while on the gas that was in the carb bowls. The pump should put out aboiut 7oz in 30 seconds at 3,000 rpms

Sure..some put a gas can in a bag and run the line to the pump. I have even hooked up a water bottle. I drill a hole in the cap to match a tube, cut the bottom off and use it to reseal the bottom after you fill it with gas(just reverse it and shove it in the open end) and hooked that directly to the #3 carb gravity feed not safe but it works..or hook to the pump still not safe but it works. I have one I keep around the shop to provide gas when working on engines in or out of a bike. You have to figure out a way to keep the bottle upright, I tie mine off to the frame with some wire.

The lines can clog. You can clear them using either a speedometer line cut to length and inserted in a drill then drill through the clog, you can also use an old clutch cable the same way only be sure the drill runs opposite the direction of the cable winding so not to unravel the cable.
Run it just till it moves past the clog, no further.

So long as the level of fuel is above the petcock`s level yes. You can open the fuel cap and see where the lines exit the tank, so long as fuel is up above them.
