Hello I am wondering if anyone has had a vacum pump leak in there dodge cummins. I have a 1997 ram with the cummins engine i installed a new power steering pump with a new coupler and three seal kits in the vacum pump, but it still wants to leak at the seal area on the coupler. Anyone can help me
Thanks Harvey
