7100 Bleeding screws not tightening

[Zot]

I rqan the fuel out on my 7100 HST. When I did the normal procedure of loosening the bleeding screwing, I noticed that both of them would not tighten afterwards, and now are leaking fuel.

Is there a trick to tightning them? I find it odd for both screws to go bad at the same time.

Thanks!

I can't make anything out in your picture.

Where is it leaking?

The pic is front the 7100 manual. I think, from the bleeding screws. When I close the fuel off, it stops, but when I open it is pretty steady, but hard to tell were from but it seems the bleeding screws to the "ficture"

I put the pic of the parts and it should one of these parts that are leaking.

If you can't figure it out, take a picture of what you have in front of you.

Sorry I am away from the tractor a bit, but https://www.manua.ls/kubota/b7100hst/manual?p=40 shows closer to what I see, where there are 2 10mm bolts over the fuel petcock, and 1 12mm to the right. The leaking is froom the 2 10mm bolts. They hand tighten to a point, and then just freespin. The 12 mm bolt tightens just fine.

This does not match the parts diagram at https://www.messicks.com/catalogs/kubota/b7100hst-d-old-type-s-n60163/fuel-system/t05900-fuel-filter or https://shop.kubotausa.com/oemparts...6000-fuel-filter?lid=6076dff24f231b5030d5ad1a which is also different from the one you screenshot. So maybe I have a different fuel system installed?

Thanks so much! When I get back to the tractor I will take photo.
