It's a good question that I have been pondering since a 280Z fuel tank is almost 40 years old. Therefore, there is a good chance there is rust inside and also there is a good chance that you are restoring a car or trying to troubleshoot a fuel problem. Much has been said about "restoring" a fuel tank. That generally means cleaning it out and sometimes lining it with a coating. Therin lie the problem. At the fuel outlet port (the one that goes to the fuel pump) there is a baffle screen. The baffle, which is a cylinder screen attached to the bottom of the tank surounding the outlet port, can get plugged up with the lining compound.

A 1976 Datsun 280Z may sputter due to several factors, including fuel delivery issues like a clogged fuel filter or failing fuel pump, which can restrict the flow of gasoline to the engine. Ignition system problems, such as worn spark plugs, faulty ignition coil, or bad wiring, can also cause sputtering by preventing proper combustion. Additionally, issues with the air intake system, like a dirty air filter or vacuum leaks, can disrupt the air-fuel mixture, leading to sputtering. Regular maintenance and diagnostics can help identify and resolve these issues.
TPS (throttle positioning sensor) Haynes manual calls it the throttle valve control i believe. take it off and clean it inside and out or just buy a new one for like $20-$30. 9 times out of 10 it is the TPS
On my pickup it seems like it is a 12 gallon gas tank

For a 1978 Datsun 280Z, the alignment specifications typically include a front camber of -0.5 to -1.0 degrees, front caster of 3.0 to 4.0 degrees, and a toe setting of 1/16 inch to 1/8 inch toe-in. The rear camber should be around -1.0 to -1.5 degrees, with a toe setting of 1/8 inch to 1/4 inch toe-in. It's important to consult the vehicle's service manual or a professional for precise specifications and adjustments, as they can vary based on factors like tire size and suspension modifications.
Does it feel more like a fuel starvation or an electrical glitch? You rterm die needs some clarification as in, you step on the gas and nothing or sitting at idle and it quits or all of a sudden I lose power and lights. To make a wild guess I would say with what you have posted change the fuel filter and then start looking at your fuel pump. If it's electrical, I would look at battery connections first. Remove, clean, tighten. There's a start for you
I've seen several pictures on differend sites that show it on the fender by the battery but mine isn't there and I have yet to find it, hope it keeps working. Sorry, I tried like crazy to find it on mine for you. Best of luck. P.S. If you find it please post the location for the rest of us.
Baffels are sections inside of the actual fuel tank which are like dividers.
The fuel pump is not visible. The fuel pump is inside the fuel tank.
The fuel pump is inside the gas tank.
Its Inside Your Fuel Tank. It Looks Weired.
