ballast resisters

thanks nm9stheham! so I first pumped into a m5 gal tank with the coil plug pulled , and key turn on pump filled the can in no time , I did squeeze the line with my fingers to see what would happen , the pump stopped pumping till I let go. next I ran the engine pumping out of the can , it did fine for 15 min at idle , but when I revved it up she ran dry again , and the pump barely put any fuel back in the clear filter. so my next test I guess is to take off the filters , and run out of the can to see if that changes anything ? what do you think?
