i wanna install a fuel guage on my boat that doesn't have one. i know that it consists of a fuel sender, but messing with anything with electronics inside a tank of gas sounds pretty :nervous: so how's it work, and how dangerous is it to do?

 

they measure how much fuel you have and then they tell you.

 

:shiner:

You're quite profound.

 

:af:

 

On a serious note, in the gas tank you have the sending unit which consists of a float attached to a variable resistor, otherwise known as a potentiometer. The float keeps at the level of the gas, and as the float moves the potentiometer moves the opposite. That changes the voltage sent to your fuel gauge (hence "sending unit"). The fuel gauge is actually a voltmeter (if you are familiar with those). Instead of 12 volts at the top and 0 volts at the bottom, you have an "F" and an "E" printed on it. Does that clearify it? Hope you have some electronic knowledge.

 

My friend's SUV has an LCD screen that tells you how many miles to empty. I want that in my car.

 

That's a fuel computer..... nothing new. The 1984 Corvette had it first, and every Cadillac had it since 1985.

 

Any way one could hook that up in an Integra? :rick:
