I have 1985 318's and my system has the "middle canister fuel filter" installed with the Perko water seperators on the aft frame supports.
The Perko water seperator bowls only filter big stuff and water. The inline fuel filter (canister) gets the small junk out of the fuel but does not remove water.
Not sure why your '88 doesn't have an inline filter. Maybe they improved the Perko filter to do both water and filter small microns. The guys with later models than mine (1985) will have to chime in.
Many people have modified from the hard fuel line to the flex fuel line to prevent cracks in the rigid tubing. If you do it, get a flex line that will fit from the pump to the carb so you don't have to worry about barbless cut tubing (unsafe). (Hot subject...sorry
