Help 2008 C4500 CAT Filter replace too long

My truck has been broke down for some time.
The Fuel Filter head was leaking.
I rebuilt it and bought the kit to switch to a CAT Filter.
Everything within the Kit worked but the fuel filter is too long to fit in the space.

Has anyone else done the CAT upgrade on a medium duty (filter Head on drivers side)

What fuel filter did you use?

My big truck is broke down and it has already be towed once. I really appreciate the help.

Thanks

You need to use a spacer between the filter head and where is mounts on the engine. But really nothing wrong with the OEM filter as long as you use the Racor or OEM replacement filter.

I have the spacer but it looks like I would have less clearence with spacer.

Does anyone know if a short CAT filter is made?

I have a Duetz Air Compressor and the fuel filter isn't extremely long on it. I will have to see if the thread pattern is the same.

Thanks

I will go to Napa tomorrow to see what they have.

I don't plan to go back to the stock filter unless I no other option.

Yeah, I am no longer a Diesel Student, 50 Diesel trucks and I am still learning.

1R750 is a bit smaller but I still don't see whats wrong with the OEM filter. If you want better filtration and another inline instead of replacing one that is already good.
