First time removing this oil filter from coach.
Is this rubber gasket meant to come off?
First time I see something like this.
I had previously purchased a NAPA lube filter I installed that had the "regular " fixed gasket.
That gasket goes with the filter,it just was not crimped to the filter good enough.
And, the new filter should have one as well-- just want ONE!
One thing to always check when removing the filter is to make sure the gasket did not stay on the engine. Things don't go good when after changing the oil you see a trail as it goes down the road.
Looks like the Fleetguard is a better filter since it talks about 30 & 10 micron ratings.
I'll have to swap them out
The latest and greatest fleet guard filter number is LF14002NN I believe.

I made this mistake once. Never again type of mistake. It is amazing how quickly you can dump a fresh oil change into your driveway when you have two orings! The worst part is that is was a brand new 5.4 motor I put into a f150. This was the 50 mile break in first oil change. I was so worried it did damage at the time but 75k later it is still running great!
Left a oil filter housing drain open on a G398 Cat once,100 plus gallons down the drain.
LF14001NN preferred and LF14000NN is standard service filter Per Cummins when I check last month

I have a 2001 ISM 450 in a Foretravel motorhome.
So I have read that the original filter Number has changed. Can I find out what is the preferred filter to run.
Thank You Scott Davidson
They are kinda different on the LN14001NN. Seal seams loose and both pushed flat and fits inside filter and around the flange when installing. I doubt you could physically install two. I too had removed a Napa filter and seals are completely different . Napa was a square oring Big and the other was a L shaped seal ring

Couldn't find stats on the LF14001NN just this.

I never ever imagined spending $50 for a oil filter. Crazy expensive
