REFERENCE INFORMATION i If no fuel arrives when cranking engine, the diaphragm in the lift pump may be ruptured, allowing the fuel to drain back into the tank. There may be some water or dirt trapped in the filter already that didn’t come from the fuel that is in the tank now. Open the filter drainvalve and crank the engine for approximately 5 seconds to purge the filter, then take a fuel sample in a c!ear container. Inspect the sample for water and dirt. Replace fuel filter (para. 3-34). TM 9-2320-387-24-l FUEL SYSTEM 2-109
