T25 Idle Control Valve Vacuum Connector Hose - 1986-92 - 2.1 Waterboxer (Not DJ)

Replacement vacuum connector hose for the idle stabilizer valve system fitted to VW T3/T25 2.1i waterboxer engines with MV and SS engine codes. This short molded vacuum hose connects the idle control valve to the intake manifold and carbon filter system, ensuring correct vacuum routing for stable idle operation and emissions control.

Designed specifically for Digifant fuel injection systems, this hose plays an important role in maintaining proper idle stabilisation and vacuum balance. Any cracks, splits or air leaks within this hose can cause unstable idle speed, hesitation, poor running, vacuum leaks or incorrect emissions system operation.

Manufactured to OEM specifications with the correct molded tail design for secure fitment and long service life, this hose is ideal for routine maintenance or restoration of ageing vacuum systems on late T3/T25 models.
