any one have any suggestions on how to make the process of changing filters easier? The new o rings suck trying to get them in and then the end plate or cover goes in or on very hard should a person place the filter in the end cap first before placing in the rear tub? or can i place the filter in the housing and then put the cover on?

Don't take old oring out unless bad. Start cap in at 45 degree until through first oring, then straight in. MACK
