This is a common misconception and advertising tactic many companies use they say they have a 60 psi pump a 100psi upgrade from that then an upgrade for that when in reality it's the same pump. How you ask. All shurflo 8000 series pumps are adjustable; they have the exact same internals on them the only thing that makes them different is volume size and the pressure switch.

Don't get fooled by the mark up
