    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Fuel Gauge Sender Resistance Levels

Hey guys,

I'm focusing on my fuel tank right now (got a new petcock and such). I was measuring the resistance of my fuel gauge sender and I wanted to know what type of numbers I should be seeing. I searched around and found a post here:

http://www.thegsresources.com/_forum/showpost.php?p=1006401&postcount=36

That said it should "sweep from 0-100 ohms," but I am nowhere in that ballpark.

Empty tank, right side up ("out of gas"): 0.106 ohms.
Empty tank, upside down ("full tank"): 0.014 ohms.

Do I need to pull the whole unit out of the tank? I didn't want to because I'd have to get a new gasket and all, but I will to get it working right.
 
Ill measure the two I have when I get home and see if theyre near your readings.
 
You shouldn't need a new gasket, it's rubber, I've never needed one.

Take a look, take the cover off, clean it out, it's pretty easy.

What scale is your ohm meter reading in? If you multiply those reading by 1000 they look in the ballpark...

The mere fact you are getting readings is a good sign the thing is working...

Oh! I didn't even think to check the units. It was probably measuring in kiloohms or something. I'll go look at the meter.
