Wellll, just plugged up my Mityvac per instruction, loosed the oil filter about 3/4 turns, pumped 10 times, but the Mityvac handle will rise and rise and rise, nothing in the instructions about this, tied it down and it worked very nicely, no mess no fuss, on restart hit oil presssure in 1-2 seconds, no leaks, didn't suck with handle up, whats up????
