• Check the condition of the fuel. Some contaminants are visible, but some problems such as wrong fuel type (e.g., ethanol) are not.

• If pressure is low and amperage is above specification, check:

1) Fuel filter;

2) Fuel line restrictions;

3) Possible defective fuel pump.

• If pressure is low and amperage is below specification, check:

1) High circuit resistance, voltage side;

2) High circuit resistance, ground side;

3) Possible defective fuel pump.

• The pressure relief valve must have pressure less than 750 KPA. Delphi units are tested at 18.8% lower in pressure and meet all OE specifications.

• Install the float arm onto the level sensor of the fuel module, where applicable. Failure to install the float arm will cause the fuel level sensor to operate incorrectly and create a customer complaint. Where applicable, detailed instructions on how to properly install the float arm onto the level sensor are included in the fuel module service kit.

• Examine the fuel tank and fuel module bucket for contamination. If contamination is found, the fuel tank should be drained and cleaned before installing the new part. Also, look for rust inside the tank or bucket of the fuel module, which indicates water in the fuel delivery system.
