fixing a summit 850 my wife totaled and looking for info on the oil pump. There are 4 hoses 2 have clamps and 2 with check valves don't appear to have had any clamps holding the hose to the pump. Is it true there are no hose clamps on these two with check valves? Looking at pumps on ebay I see in the picures there are also no clamps. Can someone confirm?? Thanks!!
