My M1008 gas gauge does not work and I am trying to find the correct gauge. If anyone lives around Magnolia Texas, please contact me so I can get this figured out. Thank you.

The sender in the tank or the dash gauge ?
When searching for parts it doesn't matter what year your truck is , search for 1984 K30 with a 6.2 Diesel.
Also where is Magnolia ? the site rules require you list a state .

Magnolia, Texas. Thanks, I’ve never worked on a truck like this and this is just one of the things that has to be fixed

Send me a message via rengle523@comcast.net I have lots of original good parts. Good Luck. But first I would clean the ground on the frame and install a new grounding washer and self tapping bolt. Worth a try.

Check your connections behind the gauge. One is ground, one is resistance from the fuel tank sending unit, one is 12v.
Many people have issues with the resistance signal not making it to the gauge.
For me, I lost the 12v powering the gauge.

I’m 100 miles or so from you with a few spare gauges as well.

What is the gauge doing exactly? If the needle just stays over past F then that is normally a sender issue. You can reach in over the tank from the drivers rear wheel area. That is where the ground wire several people already suggested you clean is on top of the frame rail. Once you clean the ground and bolt it back down. Reach in and make sure the pink wire is securely plugged into the sender.

If you don't need it to read "Diesel Fuel Only", any fuel gauge from a 73-87 square body PU or up to 89 Suburban will work. My original was stuck at 3/4. Swapped in a spare I had for my 75 C10 and now I have a working gauge. Just have to ignore the Unleaded Fuel labeling. May eventually get around to swapping the back plates.

As others have said, don't assume a bad gauge without checking the wiring and sender. Of course, the gauge is easier to swap then the sender unless you have the bed off.
