Anyone any gen on changing this out of an spi tank?

drain the tank, take the sender out & you should have enough room to get at it

I took the pump out the tank and couldn't get my big daft hand in lol :)

In the end just popped the two plastic things out of each tank and swapped them,done in about 5 minutes!
