(4) The process of crimping has been improved in the location that is shown. The Fifth Improvement
The length of the bolts that secure the fuel transfer pump to the HEUI pump body have increased. The torques on the bolts that secure the transfer pump to the HEUI pump body have also increased in order to improve durability.
HEUI pumps that have been returned from the field have been inspected and broken bolts that connect the fuel transfer pump to the main HEUI pump were found.
The major symptom that is related to this issue is an oil leak between the fuel transfer pump and the HEUI pump.
The bolts that make this connection were lengthened as well as the torques were increased in order to provide a better connection.
This improvement was effective with the following part numbers: 319-0607, 319-0674, 319-0675, 319-0676, 319-0677, 319-0678, 319-0622, 319-0610 and 319-0680

(5) Location of the three bolts that have been lengthened and increased torques have been applied. Note: The applications that utilize an electric fuel transfer pump also have this improvement for the cover that goes in place of the mechanical fuel transfer pump.Note: Refer to Special Instruction , REHS3830 for the following items: parts information, installation of parts and torque procedures that are related to this improvement.All current remanufactured part numbers are being built with the latest improvements. A list of all the current new part numbers and the part numbers of the remanufactured equivalent can be seen below.
