    Just a follow up. As luck would have it I filled up and got a bad tank of gas. Lots of water. While the tank was being drained and serviced, we tested the sender and it was bad. New one on order.

    Thanks!

    Whoa there. Don't send that man up under the dash yet. Fuel gage problems are almost ALWAYS sender problems. That is easily accessed from the trunk floor. Ground the wire there and turn the ignition on briefly and see if your needle doesn't go all the way up. As soon as the needle gets near full turn the ignition back off so you don't overheat the gage. If the gage goes up properly, then the problem is the sender.

    Before you do any work behind the dash, disconnect the battery. Lots of places to short across back there.

    At least it's not half empty like one car I owned!

    Sound like Fun? It IS!

    No Lucas Electrical's though!
    That position sounds like a young mans game. Lucas may be the prince of darkness, but there is a nice flip access panel for most things 🤣

    started a topic Speedo / Tach / Gauges: Fuel Gauge always half full

    Fuel Gauge always half full

    My 64 Hawk’s Fuel gauge always reports 1/2 a tank give or take a line. I filled it up today, gauge moved Briefly near F then settled at around half a tank.

    Sender or perhaps a sticky gauge? How do you access behind the gushed? Just the few visible screws on the panel to reveal the gauge mounts and wiring?

    Thanks!
