Those fittings can be put on the sending unit (or filler neck), which would have to come out. Not sure on complexity in a van.
There's something to be said for having excess capability... If I had that pump in hand I'd use it. Push fuel through a 10 micron then 2 micron filter, and then into the stock head for water separation.
Bulletproof filtration, pressure control (as injector pump ages you can up the pressure to restore timing), cheaper/easier filter swaps... I can't really think of a downside except fussing with the tank to put in nice fittings.
Should probably drop the tank and replace the showerhead anyway.
As a personal preference I'd put the regulator after the racor/additional filter(s) so they get full flow. I'd also tee in a gauge where the vacuum sensor is on the stock filter head to get a no-bull this is what the IP sees pressure reading.
