i have broken the smaller of the breather gubbins that come off the rocker while changing hoses in my quest to finds splits ect. there the spinning top one, that comes directly off the rocker and a small one that goes the the inlet via a small i.d vaccum hose. my question, is this neccesery or can it be bypassed. i understand those that use a alloy sep tank must bypass it ordoes the nice fabbed alloy one have internal gubbins? also, theres an arrow, does the arrow point toward the inlet or to the rocker?? a bit pathetic i know but its annoying, my missus already has a black eye. dont make me hit her twice in one day seriously though, thanks as ever if you can help

 

can anyone help??
