Lambretta air bellows drain plug screw with nut and pipe, stainless steel, MB

Lambretta air bellows drain plug screw with nut and rubber pipe made in stainless steel and designed by Mark Broadhurst.

If your motor suffers with spit back and tends to fill the air bellows pipe up with fuel, then this is a neat idea for you.

Simply drill a hole in your rubber bellows so its at the bottom where fuel collects, fit the screw from the inside out, fit the washer and nut using a bit of loctite and nip the nut up, fit the rubber hose and position the hose so any excess fuel that builds up drains to the floor.

No more flooded engines and a cleaner motor.
