Hi everyone,
My dad has a 1963 Corvette, Fuel Injection with a Rochester Carburetor ....it has been in storage & not started in 20 years. Unfortunately, I can see there is gas in the tank. Dad wants any recommendation on the proper procedure to attempt to start it. She's super pretty, and eventually will be mine so I am concerned. Any help is appreciated. Thanks, Lee
I would change the oil and radiator fluid. Then disconnect the fuel line to the gas tank. Start the car by running a line to a small gas can so gunk won't come up from the gas tank.
You will use a new rubber fuel line going from a gas can on the floor directly to the carb to avoid as much old gas as possible. You will not be able to avoid ALL of the old gas.
You should also pull the distributor and use a special shaft to to drive the oil pump an prime the engine to avoid a dry start. I've seen them on Amazon. Otherwise you'll have a dry start and could damage some bearings.
Also, before you drive it, you will have to flush the brake lines of the old fluid. You should really inspect the lines, inspect the wheel cylinders and insure that the brakes are free, and that there are no fluid leaks. Best to put jack stands under half the car at a time to do the wheel inspections with the wheels off. When you are confident there are no leaks change all your fluid. Buy 2-3 times as much as you think you need because after 20 years you really have to flush the system especially if any rust comes out in the fluid.
