Has anyone else seen corrosion inside their fuel tank in the threaded area of the filler neck? Every time I remove the filler cap it seems to be more corroded. Not sure if it's just mine, or are others seeing the same type of issue. I'll tell you, it urks me just a little bit more each time I see it..... I would appreciate some feedback on this annoying issue.... I am thinking about submitting a warranty claim on this, especially if others are not observing the same issue.....

Sincerely

I guess I’m confused, what in the fuel filler neck or the cap is a ferrous metal that can rust? Aren’t these filler necks and caps all plastic :unknown:

They were plastic on the Gen-1 2-series but it appears JD is mirroring the issue that recent 1-series owners are having. According to the parts illustration JD is putting a threaded insert and chain in the top of the tank just like on the 1-series (which is also experiencing rust and corrosion issues).

I'll take a look as well. Haven't noticed anything to date but to be honest I haven't looked too hard.

Mine had the issue pretty bad. I ordered a replacement metal neck and it hasn't started again yet. Maybe the new parts are better quality plating.

How do those metal sleeves come off? It appears to be crimped onto the plastic filler neck?

Any info on replacement is appreciated. Did they give the part under warranty?

Thanks

Sincerely

Man that looks awful Joe. Mine doesn't show any corrosion at all. I have probably 220 hrs on my 2017' 2032R. Stored indoors. Maybe it's a northern/snow issue. Whatever the case it's definitely not something that you caused. I would have a discussion with my dealer and see what they say.

Same Big, no issues with mine. About the same amount of hours as yours.

There are 4 metal tabs you just bend up so they stop catching the plastic tank. Then the metal insert unscrews (normal direction). I had to tap on one of those tabs with a screwdriver and hammer to initially loosen it. 2 min replacement.

I didn’t bother with warranty. I know I should have, but the part was cheap enough that I just ordered from GreenPartsStore since that’s so easy.

You want the metal insert and a replacement o-ring that goes under it. L80418 and L112337.

Looking at my records I replaced it 3 months ago and it hasn’t started rusting yet.

I also removed the chain while I was at it. Otherwise I would have needed to replace the rusting chain too.

I have the same metal insert on my 3039R, two years old, 280 hours.

I haven't seen any signs of corrosion and since the 1025R thread, I have been looking.

No rust at all but it never sees the cold either.

I mentioned in another thread, why in the h*#l does JD feel using metal parts in newer 2 and 3 Series tractors' fuel tanks is necessary! Maybe it was intern engineers that decided the design!:mocking:

I assume the 1 Series is still all plastic.

Nope! The newer 1-series also have the metal insert and owners have been complaining about the rust. In fact, it was the 1-series owners who first exposed the corrosion problem.

Are those who are experiencing rust using additives for diesel fuel. Like anti gelling additives?
