Rust Porsche

How do I fix my 1972, 914 Porsche that has been sitting in Florida’s sun for at least 4 years?

This Porsche was running fine before it was not used. Now it has not been run for at least 4 years, and has been sitting uncovered outside in Florida’s weather.
I need to know how to revive her. I do know that the first thing i should do is look to see if there is rust in the fuel system, but unfortunately that is all I know. If I fix this Porsche it will be my first car, so I am very anxious and very confused as to what to do? Please Help.

Thanks, Danielle17

The other answers are wrong.
Four years is nothing.
There should be few problems, as long as the air cleaner is still intact.

The fuel will probably be fine.
It is only vented systems like lawn mowers that lose volatile fuel components over time.
A 914 is sealed, and will probably have no problem, and the Florida heat will not have hit the fuel tank.
You will need a new battery, and check the oil.
Start it with a little ether first, and the old gas will probably work.
If not, only then would I bother draining it and replacing it.
I also would not bother changing the fuel filter for a week, after it has collected anything that built up in the tank from sitting.

If it just clicks, don’t keep trying.
Pull the plugs, spray a little WD40, and try to turn it by hand.
You can stick a large screw driver into the fan through the timing port, to get leverage.
If it won’t turn by hand, (which would be likely if the air cleaner off), I would pull the heads and heat the pistons with a torch to free up any cylinder corrosion, but you can also just put it in 5th and tow the car if you want to be risky.

There will be rust in the fuel system, but the filter is excellent, and will take it all out.
Change the filter after a week and then again in a few months.
A can of dryer every fill for a few months is a good idea also.

I have done this dozens of times. The Florida sun has no effect on anything mechanical. The interior, paint, exterior rubber, etc., could be dried and cracked, but nothing mechanical.

The brake lines will also be fine. I would change the brake fluid, but don’t pump down too hard or all the way when bleeding. There will be some accumulation in the master cylinder, so you don’t want to force the piston all the way to the end, over this, or else you will rip up the piston seals. Just bleed lightly, without going all the way to the floor.
Do not have the rotors machined. Surface rust will quickly rub off, and it almost always does more harm then good to turn rotors.
Just tap on them with a hammer, to vibrate them loose if they are frozen to the pads. Or use a drift and hammer on the pads. Make sure they all are free enough to turn before trying to drive, or you will overheat a wheel bearing.

Florida is not hard on a sitting car. What is bad is a place like Chicago, where they use a lot of salt. That quickly corrodes everything. After 4 years sitting there, it is unlikely you would be able to get brake bleeders open even.
