Type 25 Water Hose - Inlet Manifold To Carburettor - 1900cc Waterboxer

This rubber water hose connects the front of the carburettor to the right-hand side of the intake manifold on all VW Type 25 (T3) Transporters fitted with 1900cc Waterboxer petrol engines (DG code), produced from February 1985 to July 1992. It forms part of the cooling and automatic choke circuit, circulating warm coolant between the intake manifold and carburettor to assist with fuel vaporisation and smoother cold starts.

Manufactured from high-quality rubber reinforced with a fabric lining, this hose offers excellent resistance to heat, pressure, and coolant chemicals. It maintains flexibility while providing a snug, leak-free connection between components — ensuring consistent engine performance and preventing coolant loss.

This replacement is designed to match the original Volkswagen specification, making it a perfect fit for both stock restorations and reliable daily drivers. Over time, the original hoses can become brittle or cracked, so replacing them is an important part of cooling system maintenance on Waterboxer engines.
