Per OS Engine specs, they recommend 2.5mm Inner Diameter silicone fuel tubing for their engines. So, I just checking all my nitro fuel lines and noticed that they are all smaller then 2.5mm with the exception of the align green tubing. All my Dubro and assorted other brands seem to fall between 2mm and 2.3mm-2.4mm.
Even my kyosho tubing is advertised as 2.4x6mm.
I was planning on getting some new fuel line to replace everything for the summer coming up, but now I'm stumped on what to get. Is running smaller line going to choke out my engines or make tuning difficult? I really like the transparent blue colored line, so I don't really want to use the align stuff. Any suggestion?

I think you're picking flysh*t out of pepper. 2-2.5mm ID will work fine on most engines.
