Yes kev. I bent the float arm to shorten it but may have not allowed for the full travel up.

It seems to read low all the way up the scale.

I might have to "re calibrate" the needle. I've been searching on mx5 westie builds and they have done it. I am planning on getting rid of the original gauges after iva and going for something like a koso dash.

Build cost.... seems to be spending more on tools than car bits at the moment! (they will be handy in the future though).
