Don, It is an aluminum elbow....
I have seen those at Surplus Unlimited in Daytona on ISB (US92) If you are not in a big hurry I will check for you in the next couple of days. Only venture out of the woods when it is absolutely necessary..  When you become semi retarded it is hard to get motivated on anything ! Welcome to CSC, you did just fine on your first post with the pic and the right section..

My new tank came with the tube built in it so you only need the 3/8 fitting. They also put two input fittings in I’m thinking maybe they thought I was putting twins on so I plugged the second . Now that it’s there would be good back up if I had issues with the one in use.

Don't use brass or bronze fittings in aluminum on a boat!!
 Only use another aluminum fitting, or preferably a stainless one. You can get a stainless elbow and then thread your brass fitting into that, or get a straight up pipe to hose elbow. Something like this:  https://www.amazon.com/Brennan-5502-...t%2Belbow&th=1 Or this:  https://www.amazon.com/Stainless-Ste.../dp/B00ZY5IFAI Of course you'll have to size it for whatever size boss you already have welded into your tank.

aluminum elbow
Wow , Can't believe all the positive response on the Tank elbow, Did have one shipped from Great lakes skipper (Wisconsin) See Pic . They advertised Aluminum . But I believe its stainless very heavy. Magnet sticks to it. called them they weren't aware . wasn't sure if this would work . That Aluminum piece had been in there a long time. Guess I was looking for the same thing . Had a brass one from lowes in the picture probably wont use that one. Oh the Brass barb fitting had been in the old alum Elbow
. thanks again for all help and experience on this . John

Anti-siphon valve on fuel tank elbow
After I followed Bushwacker’s advice and added a fuel vacuum gauge, I discovered two things. 1 too much vacuum due to flow restrictions snd 2- an anti-siphon in my fuel tank discharge. After I drilled it to remove the ball, my vacuum dropped in half to about 2” Hg. Have been told not to run ETECs too lean.

I’m am not a materiel engineer but when I google aluminum and stainless togeather it’s says the 2 act like a Bettery and cause Corrosion . Looked at my old 17 year old tank with brass and aluminum and it was clean as a whistle. I know when I changed windows on the beach here in Florida some that were installed with stainless had corroded thru the holes leaving the caulk holding them in. Again don’t know much about the science .
