Chrysler Fuel Injection Tester INSTRUCTIONS:

1. Review pre-test information on the reverse side of this sheet.
2. For systems with Schrader valve connection on the fuel, connect the valve hose connector to the gauge assembly, and thread to the valve on the fuel rail. Hand tighten only. Do not confuse with the air conditioning system.
3. If there is no Schrader test port, disable the fuel pump by disconnecting or unplugging the electrical connection.
4. Disconnect the fuel line on the supply side, using a rag around the connections to avoid spilling fuel. Insert the tee assembly, and attach to the test gauge assembly.
5. Re-activate the fuel pump, start engine, and observe pressure.

Pressure readings for multi port should be:

4 cylinder                      40 psi

4 cylinder turbo           55 psi

V-6 Chrysler            45-53 psi

For Chrysler TBI readings should be:

1981-85                   34-36 psi

1986-90                         15 psi

1991 early convert      15 psi

1991 others & Up        39 psi

Always check with the manufacturer to confirm proper pressures.

Lower than recommended pressure usually means a problem on the supply side of the system. Likely causes would include a damaged or restricted fuel line, clogged fuel filter, defective fuel pump or regulator, or improper tank ventilation. Higher than normal pressures usually means a problem on the return side of the system. Likely causes are a damaged or restricted return line, a defective fuel regulator, or poor tank ventilation.
