Storage

NOTE: It is highly recommended that a fuel stabilizer, Ford Part Number E8AZ-
19C544-A or an equivalent additive be used for any length of storage. It is
imperative in any application where the fuel will not be consumed within thirty days.
Ford Fuel stabilizer comes in an 8 fl.oz. bottle for consumer use and should be
available through all Power Products Distributors. The correct ratio is 2 oz.
Stabilizer to 5 gallons of gasoline. Without the use of an additive, the unused fuel
in your fuel tank can and will go sour in a very short period of time, causing varnish
and contaminants to form. This causes problems in fuel delivery by clogging fuel
injectors.
Storage - One Month
Add fuel stabilizer (see previous note).
While the engine is running, treat upper cylinders by spraying engine fogging
agent (from your local aftermarket supplier) into the air intake for about two
minutes. Open throttle for short burst of speed, shut off engine and allow it to
come to a stop while continuing to spray into air intake.
Leave spark plugs in holes or seal spark plug holes with suitable threaded metal
plugs and cover all openings into engine with dust-proof caps or shields
(suitable non-hygroscopic material).
If engine is less transmission, spray flywheel and ring gear with mixture of one
part recommended engine oil, and one part Stoddard Solvent or equivalent.
Check coolant protection. Store indoors in dry area.
Storage - Indefinite Period
Add fuel stabilizer (see previous note).
Drain crankcase completely and refill with recommended engine oil, (SAE 10)
or equivalent.
Run engine until completely out of fuel. Gasoline only: Restart and run on
unleaded gasoline, mixed with stabilizer, for at least 10 minutes. While engine
is still running and at completion of above run, treat upper cylinders by spraying
fogging agent into the air intake for about two minutes. Open throttle for short
burst of speed, shut off engine and allow it to come to a stop while continuing
to spray into air intake.
Check coolant protection
Disconnect and remove battery.
Clean exterior surface of engine.
Leave spark plugs in holes or seal spark plug holes with suitable threaded metal
plugs.
Seal all openings in engine and accessories with non-hygroscopic material.
Mask off all areas to be used for electrical contacts.
Make sure all surfaces are dry, then spray all taped openings, all engine
accessories including ignition wiring, and all exterior surfaces of engine with
Insulation Compound.
If engines are equipped with automotive type clutch, block clutch in slightly
disengaged position so that lining and pressure plates are not in contact.
