No. The parts are all the same. The adjustment is made with the injectors. The minute amount of extra fuel the 1K uses means nothing to the pump.
You're already having issues starting the thing, according to your other thread. Why add another variable?
Buy a new o-ring, and filter, and do it right.
Agree; to do it right you'd replace the fuel filter and the large flat bottom sealing O-ring tank flange while the tank was off.
But thats 10x the work! and mess syphoning gas. When you can just unplug, swap, re-plug & and play. (unplug 3 hoses; and one electrical connector)
BTW - No real issues aside the hesitation; after being stored for couple of years; once it turned over it fired (started) right away
