50lb sender.jpg
Sometimes you find something really good on Ebay. This was listed as a B6A-9278-A oil pressure sender and the box was labeled as that. Pictures weren't real clear but I noticed the 6V 50# writing on the box. I could also see the wiring connector was not the same as the B6A's (I have a couple of those NOS left). Buy it now was $32. I've been more wrong than that before. Two 50 Lb.
markings on it, I'm 99% sure it's a 48-9278.Had to use a used one when I did the 42 as they've become very scarce. Made my day!
