Hi Guys,
I just joined the forum. I bought a 77 280Z 3-speed auto.The car has been sitting for about 4-5 years. We had to load it on the trailer. It is clean inside and no serious rust issues.
I checked the transmission oil and it seems to be in a decent color. Engine oil was dark.
I am planning to take the engine and trans pans off and clean them as much as possible before putting the new oil and try to start it up. Brake system also needs clean/flush.

There seems to be a thermal/vacuum switch on the top of the engine - just left to the valve cover. It has two ports but one is broke. Anyone know what this switch is for? and replacement part#?

Would appreciate some advice before I start to do anything.

Drain the gas tank. Put fresh gas and flush the system. Disconnect the fuel line a the return to the tank. The pump will run for about 5 seconds each time you turn the key on. . Change the fuel filter.
