The same size that it has in there now. The size you'll order from the parts store.

"What size"? LOL. The correct "size", of course. By necessity, the new one must be the same as the original. Or are you weakly attempting to ask about the pressure or flow rate? Again, it must have the same specs as the vehicle originally required - which is dependent on the model, engine, and fuel type -- which you of course, FAIL to state.
