Put more fuel in it too,my truck started running out of fuel at 1/4 tank.
I'm betting that you just have a loose fitting like Whitmore said.
Or your VP 44 is T.U. again
Just take the fuel line loose at the IP,and run it into a coffee can or something,once you have good flow there then put it back on,bump the starter a couple of times to make sure that you get the air pushed up out of the IP,then loosen #1 and 3 if I remember right,then crank on it a little till things start blapping,then tighten them back up,should run.
