Steve,

I removed mine this summer and I have the original senders like you...unless something has changed, they should just slide right our and then you need to turn them ona 90 degree angle when you get to the float...

how high have you been able to get them up?

I've got the sender to the point you can remove two screws and the sender is in to peices. the remaining part seens to have a round plate which i can't get past the opening in the top of the tank. Past that I can see the float arm so I can't get to the point of turning it the 90 degree angle to get it out. THANKS !
