If the primer suction line was damaged, slide the carburetor back onto the mounting bolts.

Attach one end of the new fuel line to the incoming fuel port on the carburetor.

Move the fuel line through the primer bulb housing and hold the primer bulb up to the fuel line.

Mark desired length and cut to size.

If the old primer suction line was intact, you can measure and cut a new piece of fuel line to the same length and attach it to the intake port on the primer bulb and intake port on the carburetor.
