365 engine. Use of this procedure will clearly define the leak location. When a fitting and

adapter leaks on the high pressure pump, the technician can easily hear the leak while

pressurizing the ICP system with air. When the turbocharger is removed, the leak is heard at

the turbocharger drain tube.

1. Pressurize the ICP system with shop air (at least 100 psi).

2. Leave the shop air on the ICP system until a leak is heard at the turbocharger drain tube

(this will be the IPR, STC fitting or the Branch Tube leaking).

3. Disconnect the IPR and leave the engine harness disconnected.

4. Install the IPR breakout tee and energize the IPR with 12 volts and ground.

5. The leak should disappear when the IPR is energized, if not there is a very good

possibility the fitting and adaptor are leaking.

6. It is highly unlikely that the Branch tube is leaking. If it is leaking it will be the result of a

crack at the brass weld area of the tube to fitting block.

While performing the STC fitting replacement the technician may find that the branch tube is

bent out of position such that the male STC fitting and branch tube adapter does not mate

evenly with the branch tube block. Under normal conditions its acceptable to bend the tube

back into position with a screwdriver rather than replace it unnecessarily. Carefully pry the

branch tube block back into position so the branch tube adapter lines up with the branch tube

block and the mounting bolts can be installed. Complete the repair by tightening the adapter

bolts and pressure testing the ICP system again to verify that the leak has been fixed.
