The rear portion of the case (handle end) needs to be removed 2 long screws on top 2 shorter on the bottom. Take note of wire attached to top of coil coming from on/off switch. Choke knob will slide thru case. Fuel line is in 2 sections connected with a coupling.
Fuel line is 3/16" od x 1/8" id. Fuel line going into tank needs to be cut on an angle to slip thru hole. Route one section of fuel line into tank first then with long nose pliers or a hemostat clamp pull reach into tank filler neck and pull line out thru opening leaving enough to attach fuel filter.
Leave about 2" extending past case towards the carb. Then route another piece of line thru hole in air box near carb going to fuel inlet. When putting case back together join both sections of fuel line together with coupling.
