(6) Motorcraft PM5 Power Flush Injector Fluid, 8oz, Use W/ Fuel Injector Machine

MOTORCRAFT PM5-6. Condition: New.

PLEASE NOTE: THIS IS FOR USE WITH A FUEL INJECTION FLUSH / CLEANER MACHINE ONLY. THIS DOES NOT GO IN YOUR GAS TANK. FOR PROFESSIONAL USE ONLY.

Apparatus
The apparatus must be comprised of the following equipment as a minimum. The apparatus must
have a solvent tank with a volume of at least 3 pints. The tank must be capable of connecting to the
vehicles fuel system to feed fuel to the engine, preferably before the fuel filter. The apparatus must
have means to supply and control fuel under pressure to the vehicle’s fuel system, for example by an
electric fuel pump, to allow the engine to run using the gasoline/cleaner mixture in the apparatus. A
fuel pressure gauge to measure fuel pressure is required to monitor fuel pressure. It is recommended
that the apparatus has a filter to clean the gasoline/cleaner mixture before entering the vehicle’s fuel
system, if the apparatus isn’t attached before the vehicle’s fuel filter.
Cleaning procedure
For cleaning fuel injectors first mix 8 fluid ounces of PM-5 Power Flush Injector Fluid with 2 pints of
gasoline in the solvent tank and stir thoroughly. Do not attempt run the engine on only PM-5 Power
Flush Injector Fluid. Disconnect the return fuel line from the vehicle’s fuel tank and plug the line from
the fuel injector manifold. This plug must be able to withstand fuel system pressure. Disable the
vehicles fuel pump relay and disconnect the fuel line before the fuel filter or at the inlet of the fuel
injector manifold. At the point where the vehicle’s fuel line was disconnected, connect the fuel feed
hose on the apparatus to provide the fuel supply to the vehicles fuel injection system. If the apparatus
doesn’t have its own fuel filter, if possible, make this connection before the vehicle’s fuel filter so the
fluid goes through the fuel filter before entering the fuel injectors, otherwise connect the feed line
to the inlet of the fuel injector manifold. Apply fuel pressure to the fuel feed line and fuel injection
manifold by whatever means capable/recommended for the apparatus being used, electric pump, air
pressure, etc. Check the shop manual for the vehicle to determine the necessary fuel pressure to run
the engine at an 1800 rpm idle speed and adjust the apparatus fuel system pressure to this pressure.
Check the system for leaks. Repair any leaks before proceeding further. With the proper fuel pressure
start the vehicle’s engine and check for leaks. Repair any leaks before proceeding further. Set the
engine idle speed at 1800 rpm if possible and run the engine until the solvent tank is empty. At this
point shut off pressure to the fuel injection manifold by shutting off whatever mechanism is used to
achieve fuel pressure. The engine will continue idling until the speed drops or fluctuates indicating
that the fuel supply line is emptied of gasoline/cleaner mixture. At this point the engine is shut off and
the cleaning apparatus is disconnected. Remove the plug from the return line and allow the system
to drain. Reassemble the vehicles fuel system and enable the vehicle’s fuel pump relay. Restart the
engine and check the fuel system for leaks.
