oil pressure
Oddjob:
You could try removing the pressure switch, turning over the motor and see if the oil comes out of the hole.
The 500/550 doesn't suffer with air lock like the 750 so I doubt it's that. However doing the above should clear that if it is the case.
Does holding the wire going to the pressure switch against the engine make the light go out? If so, faulty switch.

No, pretty dry up there.

No, that brings the light on. I think its supposed to, it just bypasses the switch which breaks the circuit when up to pressure.

I have removed the filter and noticed that its very deep in the housing. Its very tight on the bolt and not bouncing on the spring so may not have seated correctly.
Do you think that could be the problem ?
Tomorrow Ill drop the sump just to eliminate that.

Shouldn't make a difference to pressure, even if it wasn't in there at all. The housing floods first, then the oil is squeezed through filter material to get to rest of engine.
