The line bias valve is known as that in all the manuals I have seen.

What manual are you using?

The line bias valve blows off pressure. With a larger boost valve it blows off more pressure, the larger boost valve over comes some of the pressure loss via pump RPM
Dont worry how old you are... it is the mileage on your body that adds up.
