More messing the fuel selector - 1 hour

 My Aircraft Spruce order arrived with various AN fittings that I ordered to help with different installation options. I went to work trying the 45deg NPT fitting on the fuel selector. So close, but It won't work. Just about 1/2" too long and this is the tightest/smallest tube I can make. 


I decided to throw in the towel and just make a straight tube. This will ensure that the system will work. It's simple, easily made and can be replaced if needed. The gascolator sits a bit more forward than I want, but it is what it is.

I started to measure and sketch out the gascolator based on this final position, but as I lean into the plane and put some weight on the floor, I notice the floor has some flex/movement to it. If I commit to this setup/placement there is absolutely no give to the fuel tubing to account for any potential vibration or flex that I will have on the floor. It is likely that I will develop fuel leaks at this point. I'm beginning to see the benefit of having that "J hook" shape to the fuel line as it is more forgiving with respect to vibration and floor flex. 

I think I have to bite the bullet and order the proper fuel selector from Vans. Then I can get the exact installation I want. Crap...More money.
