    Looking for the fuel tank sending unit for 1979 to 1983 280zx. Condition is not the main concern, but would prefer if it was in working order. I am restoring a 1980 280zx and it does not currently have one. I am searching scrap yards ad well, but hoping this might be faster.

    I have been trying to start a recently purchased 83 280zx L28 but upon investigation, the fuel injectors are running wide open as soon as the key is turned on before cranking the motor. When I unplug the injectors they shut off which leads me to believe it is an electrical issue. I installed new...

    Hi, I recently bought an 87 z31 5 speed N/A less than a week ago and have been eagerly learning about the vehicle but can't seem to find a solid answer to my fuel issues.
