Fuel gauge sender - hood removal

[ericliddell]

Hi all,

I'm new here. Just purchased a used Manx and I can't wait to hit the road.

It has a few issues that I need to address before it's road worthy. I was hoping I might find some help as I'm a little bit of a beginner at working on these cars. I know just enough to get me into trouble.

First order of business is:

1) Fuel gauge (in the speedo) not working. Stuck on empty.

it's a combo speedo fuel gauge, I'll enclose a pic. Everything seems to be hooked up correctly and I'm dreading what I hope is not the issue. a bad Fuel sending unit in the tank.
Meaning... I'll have to take the hood off. I am dreading that route as It looks like such a daunting task to remove the hood. I believe this is a Manx 2 or possibly a knock off manx style body but I'm not sure. It does have all the tell tale signs of an original Manx. unfortunately, the back seat ID tag next to the battery is gone.

Looking for any trouble shooting help and possibly instructions on how to remove the hood and best replacement fuel sender I would need if indeed that is the issue. tank is currently about 1/2 full of gas.

Great to meet you all.

Good looking buggy. Grounding is always an issue on a fiberglass car. It looks like there is a ground wire on the speedo and the fuel sender, but I would make sure they are well grounded.

These are pretty simple cars, so taking the hood off usually isn't too bad of job depending on how it was mounted. With the fuel filler from the tank coming through the hood, you might have to loosen the tank first so it can tilt a little bit to get the hood off.

Before wrestling with removing the hood, you might try to disconnect the sending unit from the gauge and put an ohm meter to the signal wire and ground. measure it low on fuel and then again after adding some fuel and see if there is a different reading. Hopefully that will give you a direction to go next.
