I posted this yesterday on the ford sight. I changed Oil and oil filter on my Ford 1710 with no problem but when I tried to change the fuel filter I wasn't so lucky. After trying several times I finally compared the old filter to the new, although they looked similar I measured the opening at the top with calipers and found the new one was .015 smaller. So off to the auto parts store (O'reilly's open Sunday) with old and new and calipers in hand, the girl looked the number up and it was the same number as the new one but I measured it and it was the correct size. So the filter was made wrong or packaged wrong. A half hr. max job was close to 2 hrs.
 
Had that happen on a new to me pickup several year ago went to napa to get filter went to change it was labeled right but wrong filter.
 
Some times a distributor or retailer will change suppliers.

The existing stock then gets reboxed into the new supplier's box with their part number.

How could anything possibly go wrong?
 
I ran into the same problem with my Kubota B2150. Your tractor and mine use the same fuel filter.
The new Kubota filter wouldn't slip over the boss on the housing and one from my local auto parts store wouldn't either.

Since the threaded hole is .015 too small, I am going to say it was a manufacturing error.
Tooling change or something did not run the threading tool (i.e. tap) in far enough to create the proper diameter hole.
And once again production trumps quality.
 
The hole isn't threaded it slips over a boss like ACG's tractor. both filters were Wix 33264. This is a cartridge type not a spin
on.
 
Jerry, I haven't tried yet, but all looks good, This was a real weird situation. My new Kubota filter has the same number but it didn't fit along with the one from the auto parts store. I planned on sending back a package to you, but March weather hasn't cooperated yet. Be patent.
Thanks for the goodies.

It is not a threaded hole. It is just a hole in the top of filter that slides over a stem and for some reason the hole in the filter has changed size and doesn't fit over the stem in the filter housing. My original filters that fit had plastic caps that the filter media was glued to. the new ones have pressed steel caps to hold the filter media and they have a smaller hole.
It is a canister filter with bowel and when the bowel is tightened, it holds the filter tight.

I bought a genuine Kubota filter It didn't fit any better than the one from the auto parts store.
The design tolerances and materials were changed over the years. My original equipment filter housing on my Kubota B2150 would not accept the newer filters that were the exact same part number. JM sent me a housing that will accept the newer filters.
Lucky for flembo, he found a filter that fit his base, but may not be able to again. I couldn't around here.
Read down further into the post, and then comment again.

Gotchya, I have the same as pictured by ACG on a 3 cyl. Yanmar.
But mine has tin ends.
If original was plastic ended, I wonder if the plastic expanded to friction fit the spud. But when they switched to tin, they did not adjust finished hole to accommodate "no stretch" ?
I still think the manufacturing process of creating the hole is the culprit.
 
Back when I was driving a '72 VW Bug I went to replace both headlights. One had burned out but I usually replace in pairs. The big, round sealed-beam kind. Picked up a pair in the parts store, got home and replaced the bad one first. You guessed it--I got two new headlights, one bad--one good. Took me a few minutes to figure out what was going on.
