This thread is crazy to me because i was doing everything i could almost 4 years ago to just get dual fuelers let alone have 6 solid choices out there. Honestly right now the dual fueler market is flooded with options, which is good because like stated if you have different ideas for turbos, alternator, dual alternators ect ect ect you have pretty much every option you could need. 3 years ago i would have killed for just about anyone of these kits. And they all have good points
RCD has the best line set up out there IMHO, its the simplest, least amount of chance for leakage vibration ect, kinda want to adapt it to my kit lol.
Elites kit is tried and true, probably the most kits out there by volume than anyother, nice pulleys, nice kit, a tad overkill but everything is top notch.
Midwest is probably the simpliest, most effective, do your job and maintain fuel kit.. cheap too
Diesel Dr. is another price effective option, dont know much about the kit, only thing im not a fan of is the line routing but its easy to access.
