Hey Chuck and Ryan...
Frankly.... I'm getting tired of telling you guys "nice work", so .... I guess I'll say "excellent job" this time....
Seriously, as Ron stated your work looks professionally done. Kudos.
The Earls check valve in my opinion is the one to go with. It is designed for military usage, it is a flapper style valve, w/o heavy return spring to overcome. This is what I am using, after much research.
My only other comment is you may want to confirm your rear fuel loop will clear your rear clip.
Keep on rockin....
