Fuel tank lower plus airbox top I need advice asap.
 

This may be a double post. If so I am sorry. I looked for my old thread but not to be found so maybe it did not. Neways...

I got the top of the tank all made and I just need to sand her up a bit. Its time to build the bottom. But I have two snags. 1. I dont have any brass fittings. 2. I dont know what shape to use. I plan on tossing the airbox in favor of a fiber lower. Shoud I design the tank bottom like a scoop? I dont think it would kill flow too bad to have the tank connections inside the airbox. I also plan on hopefully ditching the vaccum shutoff for a manual one.
