Hi y'all, newie here to the site. I have a Cat 242B and am in need of installing a 3rd or case drain line on it so I can run my chipper (which has a 3rd line installed), and not blow out the hydraulic system on the chipper. There is a vent line coming from the top of the hydraulic reservoir on the Cat but I have been cautioned not to use that. I have been told to tie into the manifold but I gave NO idea where the correct spot is on it. Has anyone here dealt with this before? Thanks for the help, Lee
