read 5560 psi (379413 kPa). If fuel pressure is less than 55 psi (379 kPa), clean filter and replace
primary fuel filter element (see WP 0127 00).
Turn MASTER and in-tank fuel pump switches to ON position. Start engine and operate at high idle
speed (18002400 rpm). Pressure should read 5560 psi (379413 kPa). If fuel pressure is less than 55
psi (379 kPa), replace mechanical (gear type) fuel pump (see WP 0118 00).
If fuel pressure is less than 55 psi (379 kPa), replace all three fuel/water separator elements (see WP
14. With engine not running, open rear exhaust doors and observe engine deck liner for wet spots. If wet
spots can be seen on engine deck liner, remove engine deck (see WP 0336 00). Remove front and rear
cooling fan (see WP 0144 00). Loosen and tighten fuel line fittings that show evidence of leaking. If
leakage persists, notify Direct Support Maintenance. If no wet spots are found on engine deck liner,
remove left- and center-front air inlet grilles (see WP 0342 00) and check for fuel leaks. Tighten, repair,
or replace fuel lines or components leaking fuel. Check for proper operation of fuel/water separator
automatic drain system (see WP 0130 00). If leaking and/or excessive fuel consumption persists, notify
Direct Support Maintenance.
