00:00:00,000 --> 00:00:05,583
Typical steps to adjust the pressure of the low-pressure fuel supply are as follows:

2
00:00:05,583 --> 00:00:11,583
<b>Note: </b>Ensure that new fuel filter elements have been installed in the fuel filter canisters.

3
00:00:11,583 --> 00:00:15,125
Make sure that the fuel system is primed and free of air.

4
00:00:15,125 --> 00:00:21,250
Let the engine run until it drops to Low Idle speed (335 RPM).

5
00:00:21,250 --> 00:00:31,375
1. Attach a pressure gauge of 0 to 200 psi range to the quick-disconnect fitting that is located next to the fuel regulating valve.

6
00:00:31,375 --> 00:00:47,292
2. With the engine operating at Low Idle, loosen the adjusting locknut on the regulating valve, then turn the adjusting screw in to increase pressure or out to decrease pressure until 88 to 92 psi is displayed on the gauge.

7
00:00:47,292 --> 00:00:54,542
3. Tighten the adjusting locknut on the regulating valve, then recheck the reading on the gauge.

8
00:00:54,542 --> 00:00:59,417
<b>Note: </b>If the reading is incorrect, repeat steps 2 and 3.

9
00:00:59,417 --> 00:01:04,125
If the reading is correct, remove the gauge from the quick-disconnect fitting.
