After reading a few of the post I believe I may have a clogged fuel supply fitting in the tank. I was able to see the steel 90 degree fitting in the rubber grommet, but did not want to pull on to to hard and damage the grommet. I disconnected the hose leading to the bulb from the 90 degree fitting and it is holding steady pressure. Could anyone tell me the proper technique to remove the inlet hose and screen to clean it out? Does the grommet just pull out? 1997 Bobcat 773-C
