I agree, I use Viton inside the tank and never have to change it. Hi flow hard clunk with safety wire for security. Never had any issue. I use Tygon outside the tank up to the air trap and pump. I use this system for 45-320N turbines. I use 1/8" ID for 45-160N, 3/16" ID for 180-220N, and 1/4" ID for 230-320N. I get the flexible Viton and Tygon from McMaster Carr. I like Jet Tech fuel fittings for glass and Kevlar tanks and a Dubro stopper for plastic or 3D printed tanks. Just my preference.
