Here are a few fuel valves and filters available from other industries. Whether you prefer the vintage look of a sediment bowl, screw in or inline, metal or plastic, with or without built in screen, straight or 90 degree, the lawnmower supply shop can offer all. I got these from the Rotary catalog, which most mower repair shops stock or can get in a couple of days. The threaded valves are 1/8" npt, and the slip ons are 1/4".
