Product description
All Volkswagen buses equipped with a brake servo are fitted with a vacuum check valve. This valve ensures that the vacuum in the brake servo is retained and prevents pressure from the intake manifold from flowing towards the brake servo in the event of an engine backfire.
The installation direction is indicated on the check valve. On the T25, the valve is fitted between pre-shaped vacuum hoses. This check valve is supplied without hoses; therefore use the existing pre-shaped hoses that belong to the relevant engine version.
Note: Regularly check all vacuum hoses and connecting rubbers between the intake manifold and the brake servo for cracks, deterioration and other damage. On the T25, also carefully check the connection to the brake servo. A leak can reduce the effectiveness of the brake servo and at the same time cause an air leak, which can make the engine run unevenly and disturb the mixture. Prolonged or severe leakage can eventually result in engine damage.
The same check valve was also used on Mexican Beetles with a 1600cc carburettor engine as part of the carburettor vacuum system.
