This has came up before. The fancy OEM booted terminals were used at fuel senders and temp senders. I don't recall a source for reproductions being found. The basic 90 degree terminal without the extended boot will work.
A ring terminal with hex nut and toothed washer will work at temp sender but I wouldn't attempt to tighten a hex nut and washer at the fuel sender. Rotating that post could cause a fuel leak.
3/16 or #10 diameter male postThanks for the info. I would like to use the 90 degree terminal, do you know the inside diameter? Other wise I will just pull it and measure. Thanks
