CORRADO With AFC-DIGIFANT II
- Install Fuel Pressure Gauge (VW 1318) and Adaptor (VW 3118-1 and 11) between the fuel distributor test port and pressure switch. Bleed excess air from system cycling control valve with gauge upside down.
- Open fuel pressure gauge control lever, start engine and allow to idle. Fuel pressure should be approximately 36.3 psi (2.5 kg/cm2
). Pull hose off intake manifold fuel pressure should increase to approximately 43.5 psi (3.0 kg/cm2
).
- Switch ignition off. After 10 minutes residual pressure should be 29 psi (2.0 kg/cm2
). If residual pressure is too low, run the engine until system pressure is built up, pinch off Blue fuel return line. If pressure holds, replace the fuel regulator. If fuel pressure is low, check the following:
- Fuel lines for leaks.
- Fuel injectors leaking.
- Fuel pump check valve leaking.
- Pressure gauge stop-cock leaking.
