have you seen the size of the spa stuff?

or am i getting mixed up with the temp sender?

mie is in the sump, but the sump has been drilled and tapped for this as i was using the sump plug but the risk of getting the wire snagged was too great

also, the bit you need to unplug isn't at the sender end, it's loads of miles away at the other end of the wire in the gauges that i've got
