Hyd-filter not going ON???

   / Hyd-filter not going ON??? #11  
Had an oil filter for my PU that had no threads. I was kind of stuck and had to break out the bicycle and rid 4 or 5 miles to the auto parts store. I shamed the manager when I walked in rolling my two wheeler and he refunded me and provided a new filter at no cost. Needless to say I check the filter for threads before I leave the store now.
