Ok, still researching here. I did find install instructions for the recor kit and frankly do not like the idea of cutting the factory fuel line and installing compression fittings, goes against everything I ever learned about plumbing. Also, do not see the need for another WIF/ heater, so am leaning toward the nictane. My question is, does anyone have install instructions for the nictane kit and does it require cutting the fuel line? thanks.
