 I found that the cline regulater works much better the closer to the carb. you can put it.This supports your idea of line resistance being a factor in the pull of fuel. I have a OS 300 twin that I have a hopper tank and use the cline with pipe pressure to the tank and it runs flawless. I also run the cline on my webra and have it mounted 3 inches from the carb.This config made a big difference in the needle than when I had the regulater mounted further away.
The closer you can get theitems to the carburater the easier it is to pull fuel.
My experiences.I have more for later.
