Q: My Toyota fuel gauge reads empty but the tank is full — is it the connector?
A: A fuel gauge stuck at empty with a full tank indicates an open circuit at the fuel level sensor — most commonly caused by a corroded 3-pin connector at the fuel tank sending unit. Inspect the connector before replacing the sending unit or fuel pump assembly.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
