Congratulations man! You have made my wife's list of bad influences on me! (It's a long and distinguished list!)
I pulled the trigger on a 40 gallon fuel tank with in-tank fuel pump. So now some questions about plumbing:
Did you leave the vapor separator system in place?
Did you use the existing hard lines? (these guys are recommending 3/8" supply and 3/8" return lines)
Did you add a in-line filter? If so, where physically?
Did you run a vent line to the charcoal canister, or perhaps it's part of the vapor sep system?
