The British Seagull® Outboard Fuel Filler Cap Air Vent Screw sits in the centre of the British Seagull Outboard Fuel Filler Cap Assembly allowing air into the fuel tank at the same rate as the fuel is gravity feeding out through the fuel tap.
The British Seagull Outboard Fuel Filler Cap Overhaul Kit can also be used if the plastic moulding is still in good condition.
This part is suitable for all British Seagull Outboard engines except for Model 170 and Model 125.
