Anyone know the oil plug thread pitch on a 2004 Cummins B3.3? We just ordered a Fumoto Valve PN: F104N which has a thread pitch of 18mm X 1.5 but it's too small.
Can anyone help?
 
I tried. Maybe if you have the Engine number I could narrow my search, but it doesn't look good. If I had the esn I could call one of my engineering buddys and get you the info.

I can get any info you need. I wrote the ESN down today so I will post it tomorrow
 
The plug is a 22mmx1.25. That explains way the valve doesn't fit.
 
Yeah I checked out the site and didn't see one listed in that size, but the last the size list was updated was in 02.

If you don't have any luck I think Cummins offers a remote oil drain set up.

Thanks a bunch!
Fumoto web site has it listed as 18mm X 1.25. I think they need to update their info LOL

No, some Cummins...24v's I think...have a smaller drain plug, m18x1.25.

The 12v's and older ones have the bigger thread!


Or something like that...I can't remember which way it is!
