How to increase water flow AFTER the filters?

Ok, I recently installed a RVwaterfilterstore.com filter system. The filter sequence is: a 1 micron sediment filter, a .5 micron carbon filter and the final one is a metal trap canister. The campground I permanently camp at has strong well water pressure (65 psi) and great flow. After I connected the filter system the water barely flows from the hose and all the fixtures in the camper have less than ideal water pressure.

So, I would like to keep the filtration system but need an increase in water flow after the filter system. How can this be achieved?
