Draining the Fuel Filter - 100 & 400 series engines (cont’d)
14 Prime the Filter.
Early Machines
Slacken bleed screw M and operate the lift pump
priming lever N until fuel spurts from the loosened
connection with no entrapped air.
Note: If no fuel is moved when the fuel lift pump priming
lever N is operated, then the pump diaphragm may have
rested in the ‘maximum lift’ position. To move the
diaphragm, use the starter key to turn the engine, then try
the priming lever again.
Later Machines
Slacken bleed screw M and operate the priming pump P
by squeezing the body until fuel spurts from the
loosened screw with no entrapped air.
15 Tighten the bleed screw and check the filter for leaks.
Tighten connections or change seals as required.
