After untold years of using two line systems I am ready to try a three line system. The question I have is; what do you use to hold the two clunks together? I don't want them coming loose and getting the lines tangled up.

My three gasers now all have two line systems with a Tee in the line to the carb with a line from that running to a fuel dot. From what I am seeing a lot of people use a three line system instead. Is there any problem with using a tee in the fuel feed line on a two line system to fill thru as I am now?
