[T3] Update with a Bowl Full of Rust Flakes

[SCS Crewcab]

Another thing when you're storing an FI car for very long. Disconnect 
the 3 fuel lines from the pump and put them in an empty pail. Turn the 
engine over until all the gas is pumped out. Empty the pail and put a 3 
to 1 mix of 10w oil and Marvel Mystery oil. Turn the engine again over 
to fill the pump with the light oil mixture. This will keep the pump 
gears from getting gummed up with varnish from the old gas and protect 
them from corrosion. When you go to start it, make sure to pump out all 
the oil mix before you connect it back to the engine.
