cheers rod, well there is only the purple wire that you connect to the sender, then a +ve and -ve, lumination, and the 2 wires for the switch.

so im pretty sure its connected right lol. i will take it out and double check tho!

i suppose it is possible that the float is stuck down, as it was ages before any fuel went in the tank. dont really want to take it out, but if i have to i will.
