Help installing gas gauge

Well the original gas gauge no longer works in my car, and leaks out a little bit of gas, so I decided to finally change it. I bought the tools and a new repro gas guage assembly from snyders. Also bought the neoprene or rubber float due to the ethanol fuel. Is the install as straightforward as it looks?

Do I just wait until it has almost no gas in it, remove the old one, then put the new one in?
 
It is fairly straightfoward. Drain the tank to below the guage level (or lower). The tank doesn't need to be empty, just below the gauge level. I used some gasket sealent in addition to the washer when doing my install. There is a youtube video of a guy doing the install if you decide to watch someone doing it. I found it good to watch.

While it is an easy install, don't forget to be a good distance from anything that can spark and that you have decent ventilation. Gas fumes are dangerous.

Good luck. Seth
 
It has been a while since I have done one. It is important to clean the area thoroughly. Do not use a vacuum cleaner to remove debis as it will suck gas fumes into the sparking armature. You will need the two-part tool to remove and install. I do not use any sealer, but I coat all the parts with a light coat of Vasoline so there will not be any binding as things are tightened.

I also install a brass float salvaged out of a Tillotson carburetor in place of the cork or neoprene. It easily fits through the gauge opening.

Disconnect the battery before you lift the dash panel off. No smoking during the process.

Leakage usually occurs if the assembly should bottom out in the tank boss. In this case you can add an additional large brass washer.

A brass welding wire brush can be used to clean the surface of the gas tank receiver for the gas gage assembly. clean is the operative word. I used a straight edge across the 2 upper mounting screw holes for the instrument panel to orient the sight glass level line. I like using the steel 2 piece wrench set over the aluminum one. Bob
 
After you get everything cleaned and ready for installation, dry fit the parts just snug, then take a bent coat hanger and gently lift up your float wire till the float touches the top of the tank. Hold it there then look at your gauge to see if it is reading full (F). Bend your float wire as necessary to get the proper reading, then seal it all up.
 
follow above I like neoprene, I had trouble with brass leaking due to corn gas.tank only has to be level below guage

I like ray's idea of checking for full, gonna remember that one

But remember: You don't get problems when the "full" reading is inaccurate, you get them when the "empty" is inaccurate!

I find it very hard to actually fill up my tank, since the gas pump starts trying to shut off as soon as the tank is about 3/4 full....
