I can't help with jet sizes but that's your fuel pump.

No problem, so since i have installed a new fuel pump (high performance) i take it the factory fitted one is no longer needed?

Take the pump off and stick one of these on.

cheers Brian, i take it this needs to be done to ensure good running?

It won't affect the running but is wasting engine power as you will still be operating the mechanical pump but just trying to pump fresh air!

It would be cheaper to leave it on. The drag on the engine from this pump is negligible as it is pushed by a cam on the camshaft (or crank, i forget which now) not turned like a power steering pump.
