12v out of fuel, how to get running?

ok i read in here for at least an hour and it seems like vp 44s and 24 v's are all i see for restart. some pos syphoned off my tank an i hadn't noticed, so this morning when i fired up i let it run for a bit and went to get a cup of coffee it died. i went out and looked at the gages and the dang tank was about dry. i stuck a rubber hose in and it has no wet. i dumped in 10 gallons of fuel and i filled up the filter and pressurized the tank but i don't seem to have any thing pumping. i cracked injectors at the pump and nothing. i cracked the inlet line and pumped the lift pump and it seems to squirt out. i cracked the overflow valve and nothing. is there something else i can do or what? is there a procedure i should follow? i have had this happen on 24v's in freightliners but they don't have the same pump as this so i'm not sure if i'm going about this the right way.

Tighten everything back up. Crack the nut on tip of the filter canister. Carefully pressurize the take again. Wait for fuel to leak out of the nut. Tighten it. Start.

or tighten everything back up and pimp the heck out of it, about 200 strokes.
Then start it.

the little nut or the bigger one? the front one looks like a bleeder, around a 10mm. if there is fuel there then will it pump the air out of the injector pump?

ok it only comes out of the little one if i pump the lift pump should it just flow free? the filter is only 2 weeks old but is a purolator. thats all they had at advance auto so i put it on.

It is the nut in the center on top of canister. The one you use to take filter off.

running again i put air in the fuel tank, loosened screw on top of fuel filter, got fuel to come out on it's own. loosened inlet to p7100 till fuel came out, loosened overflow valve till fuel came out. cracked injectors and cranked till fuel came out and tightened when it came out on which one had fuel. then i held it to the floor till it seemed like it was trying to run. then i just let it idle for a while and brand new. that's the last time i leave my truck behind my shop where nobody can see butt-heads syphoning my fuel.
