Check the fuel pipes at the fuel tank. Remove the boot carpets, undo the 6 screws holding the tank cover on and see what the Nylon to pipe fittings look like. If they have cracks in them then they're likely to be the culprit, letting air in. Only real cure is replacement sender unit, even epoxy doesn't work too well or for long ...

I was doing a service and lift pump arm on my old one was kaput , Can't do much now as I'm in work. I'll look when I get home and bleed it again

+1. Change the fuel filter first and see how that goes

I know this has been done a million times, but what brand of lift pump did you get? Was your car working perfectly OK before the lift pump was changed?
These are self bleeding systems so if the pump is working OK then it should be a case of fit, crank it over and away you go.
