Next question about fuel sending unit

[Bearcuda]

Ok, I've established I need a 5/16 inlet fuel sending unit for my small block cuda. Next question, my friend has a new one he ordered for his 68 coronet rt but they sent him the wrong one, a 5/16 when it should be 3/8. Instead of sending it back and incurring a $20 restocking fee, he was trying to sell it to me. Would a B body sending unit work in an e body gas tank? I feel like if they were compatible then it would show it on his label.

NO it will not fit, completely different shape for inside the tank

Cool, thanks
