RE: Profile Foaming Issue...
Those tubes exiting the front of the tank are way too long and will shake the heck out of the tank. Make them no longer than about 5/8" or so. Also if you had 4 hooks like usual instead of 2, the bands would not have to be quite so tight or so many, allowing the foam to do it's job better. Use a fuel filter right before the engine. That tends to condensate air bubbles. The cintered clunk seems to work good but I haven't used them yet on my profiles and am doing okay. Man do you have some right thrust!
Good luck, keep us posted and have fun.
