Best way, is to remove from boat/ski, then with compressed air, switch from "on" and then "reserve", visa-versa, But shoot air from bottom spigot, since clogged came from tank/deteriated lines to begin with...:cheers:
If same as others....remove the center cap, and remove the screw, pull dial off to expose the black housing screw, undo that and selector will fall inside hull...:cheers:
lol...."space is tight"....no special tools, if you can recall, if you have grey fuel lines, stop at auto parts store, and pick up about 15-20ft 1/4in hose and replace the grey, along with hose clamps...:cheers:
