The fill cap on the hydraulic jack on my '72 broke. I got a PVC plug that I think will work (with a bit of Teflon tape) but I noticed the old cap has a small air hole. Is it important to have a vent hole in this cap? No doubt it is the mysterious source of fluid leaking when over filled - which brings me to another question - how full should the jack be filled with fluid?
