here we go again…
nostalgia will want you to keep the pressure tank
"modernia" will tempt you to go single line
I did my 5.5 this way and it runs great btw you will need to find a spare old style single line connector BEFORE you start or use only the fuel side of the existing 2 line connector since the "air " pressure side will be voided by these mods

the other method on engines e/w with side cover plates involves mounting a pump with a source of vacum obtained by accessing the innards of the
crankcase either by mounting a regular OMC pump over a hole drilled in " prepared for" side covers or drilling tapping and "nippling" a cover plate
for your source of vacum pulses. IF you mount a OMC pump over a small aluminum plate to "cover the cover" just drill a hole 0.25 & center the OMC pump on the 0.25 hole also drilled in the aluminum plate then using the existing bolt holes mount it all up and vacum pulses will directly work the pump from behind without the need for a third "vacum" hose to a nippled plate.
…BTW you will need that single line hose fitting BEFORE you start. You will also be plugging the small nipple behind the carb with a piece of short 1.5 inch fuel hose and small bolt. the B&Stratton pump (made by MIkuni) #808656 worked for me
