Oil & Fuel 3520 with cab fuel sensor

[Coponadeere]

Just as matter of information for John Deere cab tractor owners. I have a 2007 3530 cab tractor with the fuel tank under the left fender and above the tire. The fuel sensor sets on top of the tank inside of a recess that traps water and holds it causing the sensor to be submerged. The old sensor had a spongy foam like packing material as a seal. This failed in the water and caused the fuel gauge to read full at all times. I replaced it and solved the problem. The new sensor is upgraded with a hard shell material as packing. It appears that this with solve the water destroying the sensor. I found out that there is not recall on the failed sensor, just a part upgrade at owner expense unless it fails while under warranty. It is a $165 for the part. This my first out of warranty repair expense.

Hi, I'm gonna replace my fuel sender soon since I'm having the same problem you had. Does any one got any tips about how we reach the fuel sender on a 3520 cab? Do we drop the tank, or remove the fender? Any tips could save me time I guess!

Just received my sensor today, so no one can share a tip about how we get that sensor out?!?

You lower the tank enough to access the fuel sender.
