X1/9 Water Pump Bypass Pipe - 1500

Metal coolant pipe for water pump to thermostat bypass hose with heater and auto-choke take-off pipes.

Note: This is a substitute part for 1500 models as the heater pipe take-off is 20mm diameter, whereas the original size is 16mm. This will require a short 3/4 inch hose section and reducing adapter to the original 5/8 inch hose.
