Fuel Filter Retrofit

re: 2002 ISM 450
I am thinking about upgrading the factory fuel filter system to a DAVCO 382 set up. I am wondering if the fuel lines are long enough to connect to the new unit? They don't look like they have much room to move them around. I reviewed the Search findings for the DAVCO 382 and did not see this question discussed.
Second question: The existing facotry set up has a primary filter (Win 200200- which I hate) and a secondary filter. Is there a 3rd final filter located on the engine somewhere? I would think it would be a small (2?) micron final filter.
As you can tell this is my first attempt to understand my fuel system.

I think you will find the final fuel filter on the curb side of the motor, accessible from below.

Two fuel filters, the PRIMARY before the lift pump and the SECONDARY after the lift pump.

Have never seen a 3 filter system.  Have seen redundant systems on boats so one set of filters could be serviced while the other is in use.

No, total of 2 filters, not 2 plus 1.

You will love the Davco 382. I switched all mine over to one on my 95 Peterbilt tractor and its worked great for 5 years.When I get time I'm going to the big truck salvage and source one for my 91 foretravel.
