Easiest way is to just hook the hoses that go to the rear unit together as close to the engine as possible. May need a special connector (hoses prob. diff. size) and 2 clamps, avail. @ NAPA i am sure! Other parts stores should have it as well. If need be, cut a piece off of each hose to take to parts man for sizing. Get a metal connector if aval. at your store!!! Plastic will work but have seen some collaspe.
