I had a thought I wanted to run by others here. I have a 92 Trans Am that I need to prep for long-term storage.
We all know it's best practice to drain the fuel tank and then run the engine until it stalls to empty the fuel. We also know you should remove the spark plugs, fog the cylinders, then seal off the intake and the exhaust. All good and well, however, this process leaves residual fuel in the pump, fuel lines, fuel rails, and fuel injectors.
What IF instead I did it this way; I'd still run the car to empty on gas, but instead of pulling the plugs to fog the cylinders, I'd pour a couple of gallons of a WD-40 like substance into the fuel tank. Then disable the ignition spark, turn the key to prime the system with the WD-40, and then give the engine a session of extended cranks. The fuel pump should be able to move something the viscosity of WD-40 up to pressure (43.5psi) so the injectors operate. This would flush and effectively safeguard my fuel pump, fuel lines, fuel rails, injectors, combustion chambers, and even the inside of the exhaust at the cylinder head against the effect of fuel deterioration and corrosion.
Thoughts? Has anyone tried this on motorcycles, boats, etc.? I also have a fuel injected motorcycle I'd like to do this to.
Thanks!
