I am looking for two fittings to connect the hard fuel lines to my tank. I need the tank end 1/4" pipe thread 90 degrees to 3/8" for one and 5/16" for the other. Rock Valley where I got the tank only has AN, I checked the local auto parts store and looked through my Speedway catalog and I can't seem to find these...any ideas? Also where can I get a fuel cut off valve?

Thanks
