Fuel gauge on my D17 always reads empty. Does it have a float that can be replaced?

yes The original was cork and they can become deteriorated to the point of absorbing gas/fuel....or may be decomposed or missing entirely.
This is what I did for mine. Removed the existing float by carefully tapping on the brass or steel rod to make it round. Drilled a small hole in the end for a brass cotter key. This float for a Ford Model A fit the rod and is the right length.

this is one place to get the float; there are many others that sell the same thing

x2 The float can also slide up the rod and give an empty reading. Either way, replace the float. Move things by hand first to make sure the rest of it is working properly.

When I did the D15, I did as above but screwed it up in the long run. The aftermarket gasket seeped and ruined the paint under the gauge.
I got the replacement gasket thru Brenda at Sandy Lake and all has been well thus far.

OK, I'm a bodger..., I cut the float from a 99 Cavalier gas tank unit into two and got BOTH Troy and Milton working gauges..unless the 'correct cops' look in the tank, no one will ever know ..hehehe Jay

Mine was liberated from an early '80's Suburban... tank was junk, float was fine. Unfortunately, whenever the tank is over half full, the gasket 'round the gauge leaks... but then again, there's a spot in the tank up next to the battery that has been patched with fiberglass... apparently battery acid corroded it through there long ago... and it leaks too, so the solution: Don't fill it more'n half full!

They sell those floats on all the antique tractor parts web sites. Just use a good float, I tried a cork out of a wine bottle and it didn't work. Too small I guess.

Make sure the black type float is secured so it does not move up and down the rod. Don't ask how I know. Regards, Chris

I used the float from the model A Ford. Don't remember where I got it, but it was from a hotrod / oldie car site that was listed on here back a few years ago. It was pretty cheap. I made a small "very thin" washer out of some copper and drilled a hole so it 'just slid' on the rod. I used a cross peen hammer after measuring how far the float had to go on and whacked the rod so the washer couldn't go past that spot and like above, I drilled a hole in the rod to put a cotter key in. I put another washer on after the black float and then put the cotter key in. It's been 4 or 5 years now.
Forgot to mention, as DSeries4 said above, move the arm up and down GENTLY to see if the needle moves also. Be VERY careful doing so. This will tell you if you need a whole new gauge or not. Hopefully it will just be the float!!
