I just did a primer bulb not too long ago, but I don't remember what equipment it was on. They are generally easy to replace. First, remove anything that is retaining the bulb assembly, such as cover plate. On my Homelite chainsaw, I simply pried it out with a small screwdriver.
The replacement part itself has two barbed stubs that the two fuel line hoses push onto.
Make sure that you keep the fuel line tubes above the fuel level at all times to prevent leakage.
