I have only had a few Henry tanks , The one Op posted just looks like both the Sender & pick up to fair to left , Why ? & tank I have had not dimpled like one shown .
The OP and Eddy’s pics both show the original pickup/sender location right next to the little bolt holes in the rear lip. The other sender hole on each was added by some dad-gum hot rodder wherever he damn well pleased. No wonder they are both in the “wrong” spot.
@alchemy Yes Du!! Me working on & having stock some modified parts forgetting that 32 only had pickup & bub in one & I walk by a pick up each day 3-4 times on shelf
I had to drill out the drain plug out on my original tank. The above tanks look like original. The best reproduction tank was made by Vintique and could p*** as original, but the current one is not close.
