When I replace fuel filters, I have the new filter in the engine compartment area and fill the new filter with fuel before removing the old filter. I immediately screw on the new filter filled with fuel. This is done on both primary and secondary filters. After completing the filter swap start the coach and bump the throttle to about 1000-1200 rpm’s and it may be sluggish for a second or two then clears out and engine runs as it should.
