So I'm confused I have the 450 ISL9 and I'm doing my first yearly maintenance since the dealer did it originally when I bought it used a little over a year ago. Though I went out and bought spare parts, like filters, belts, etc.. I see the Napa Fuel/Water Separator part number on the part is 3604 installed. For some reason I bought a Fleetguard FS1065 Fuel/Water Separator as a spare part but I cannot seem to find out if this is a cross reference or direct replacement part for the Napa Part Number 3604? If the FS1065 isn't a replacement for the 3604 can someone tell me what is the Fleetguard Part number that replaces it.

Also if there's any utube or video on how to replace the 2 fuel related filters I'd appreciate it.
I guess while I'm at it I need to replace the air filter, as well, Parker Racor Eco-lite Part Number 062891010 Ecolite I pretty sure it's 13.5x15 not sure where the best to buy this or if there's a good alternative to this particular part. I'm in the Port Charlotte, Florida area.

The Fleetguard FS1003 is the fuel water separator on mine. I don't know if that corresponds to the NAPA 3604. The fuel filter is Fleetguard FF63009.

Here is where I get my air filters. Unfortunately it's gone up almost $100 since the first one I ordered four years ago. There is no alternative as far as I know.

I replaced my fuel filters (2) on my ISB 6.7 and didn't realize there was a bulb primer pump on top of the filter. At first, it didn't start and then after a few phone calls, I had to get up in there and prime the he11 out the lines. I thought moving the key to run a few times would do the trick. Ooopsie.
