Thanks to all for the replies,it's my first cobra. I was wondering what was the best technique to plumb a 90 degree fitting from the top of the tank to install a rubber hose all the way up along the filler neck which will be a piece of rubber hose that will connect the cap piece and the tank elbow. I don't know if i can tap fillet in the tank,if there's enough material,would somekind of a bulkhead fitting work if i seal it properly. Somebody suggested soldering the fitting !!
