Old or New Fuel Sender?

10 ohms full 73 empty. Re use the old tank ring or it will usually leak , The new ones are junk.

when i did mine (i replaced the float which had cracked) i re bent the shaft and ended up at 10 and 70
perfectly dry i started adding fuel in measured amounts and it is quite close now.
2 measured gallons hit 1/8th
8 gallons 1/2
