It's perfectly good mate, as long as you block the return to the meting unit off! Otherwise yes you have introduced a big air leak (like removing filler cap) and the flap in the metering unit will not get sucked down and so it will not fuel and so not start or run at all.
But it's blocked so there is no air leak.
