I should add I ALWAYS use 5/32 or 3/16 tubing for the fuel lead along with medium to large tygon and the fuel clunk I use the sulivans because they have a large opening and can be drilled out even bigger. I have had problems with 1/8" id lines. Also I never use a t-fitting to split the tank to carb line for filling the tank. I use a 3rd line and put a 90 degree upward bend inside the tank with some tygon cut on an angle at the end. Works great and to get all of the fuel out I just flip the plane over and if the filling cap comes off in flight it wont syphon out. Splitting with a T-fitting can introduce air leaks.... For the filling caps/plug I only use the aluminum bison jobs. medium size for medium tygon and large for large tygon.

Some guys will argue the the larger line isn't needed because the inlet on the carb is small. I think a bigger supply is always better. I have had dead sticks with the smaller line and much better luck with the larger line. I also barb all tubes. To get the tygon over the larger tubing n barbs I just use a little vasoline. Also helps to throw a little heat from a covering gun on the tubing prior to installing.


I like the sulivan crap traps for filtering, I only use the large one. I also filter with 2 filters on my filling jerry can before it even get to the tank...
