I want to replace the giant canister/primary filter setup with a kit that will bolt right on to the three existing mounting holes and use a nice spin on fuel water separator filter . Any suggestions?

FLEETGUARD FS1000 is a 10 micron fuel water seperator.
Fleetguard FS105 is a 20micron fuel filter

Does the three mounting holes stand off enough to mount it direct or does a mount have to be fabbed?

Do you suggest running two of the same filters in parallel? Such as dual FS1000 filters?
When placing this inline what should the original fuel lines be replaced with? What ID is the stock tubing? (I have seen in other posts that "home Depot" has parts that can be used... What tubing OD/ID am I looking for and what are the fittings that work best under the suction and are fuel resistant? If there is a write up here in SS somewhere I am missing it.
Is the pickup tube removable or is it welded and is there need to modify it to minimize problems too?

I would run an FS1000 and FF104/105.

I run a FF105, then FS1212, then a FS1000 on the pump just for longevity of filter life.

With the three filters in series does that cause any issues with the lift pump wearing out faster from the extra "work"?
To monitor the status of the filters is there a vacuum gauge that is placed in a "T" with the suction tube into the tank so you can see the suction dropping off? Is there a better way to monitor the filters and to help troubleshoot fuel delivery issues at the same time? If so what vacuum is it that is typical to see from a lift pump on a NHC250?
