Can't trust the fuel gauge on your VW T2 Bay or Beetle? It may be a faulty voltage stabiliser. A vehicle's supply voltage varies considerably depending on the state of charge of the battery, the engine speed and the demands made by other accessories. The fuel gauge measures the voltage put out by a sender that responds to fuel level – any variation in the supply voltage causes these readings to change. Stabilise the voltage and you get a more accurate reading.
Fuel gauge voltage stabiliser. Fits all VW Beetles from 1967 to 1979, VW T2 Bays from 1973 to 1979.
