Thank you for the reply. I followed the advice and bought new sending units. The old ones have proven very difficult to remove. I tried a 2 1/4 socket but it didn't budge and ended up just rounding the plastic corners. My next step is to cut them out which is going to dump a lot of debris. Not an issue on the waste but I would like to avoid it on the water tank. Any advice would be appreciated.
Thanks
Joe
