I'm using the James MK234 filter assembly. When I line up the front hole perfectly with the cowl the rear hole going into the fuel injector is a bit off. It covers up some of the hole on the injector. What should the remedy be? Is it Ok to have a small portion of that hole covered or will the engine not run perfectly? I can do some fiberglass work to adjust the hole in the transit duct so there is not any part of the hole covered. Thoughts??
