Fuel Line Fittings

  1. If leakage occurs between pipe connection fitting (union) and injection pump adjusting plate, install new seals with grooved fittings. DO NOT loosen adjusting plate, as pump recalibration will be necessary.
  2. Install new copper gasket whenever fittings are removed. Grooved end of valve carrier should be installed downward. Install other components and oil fittings.
  3. Install injection lines. Operate primer pump until by-pass valve can be heard operating. Operate engine and check for leaks.
