Easier way to change filter or to remove air from fuel system. Pull off return fuel line on IP and put about 4 psi into line going away from IP open bleed on fuel filter block let the air push about 3\4 soda bottle full of fuel, shut bleed remove air filler from return line let air escape back out of return before putting it back on IP. Engine will start right up, no cranking. Also always fill fuel filter with fuel before install. Filter should be changed every 10k for best mileage. I installed a brand new engine in my cucv and did this, the engine started on second cranking.
