I used the H9 gas filters before, it is just a tad smaller than the ones that comes with the engines, the fine nylon filter screen is the same, the filtering screen on the glow filters is not fine enough, what you are trying to protect are the fuel injectors inside the can from getting any fine debris in them, connect the in line to flow over the exterior of the filter screen, this way you will see and will be able to clean any dirt off the screen.
Good luck.
