Other models
The tank air vent consists of a nonreturn valve (A) and a sintered filter (B).
The nonreturn valve is open in both directions but to a different degree. It is therefore
important that it is positioned correctly. The short part 1) should be connected to the
tank.
Pressure test the valve in both directions.
If there is overpressure in the fuel tank the valve opens quickly at approx. 20 kPa
(0.2 kPa/cm
2
) and is completely open at 30 kPa (0.3 kp/cm
2
).
If there is underpressure in the tank the valve opens immediately.
Replace the valve if it does not function as intended.
