You're correct on the pressure of the pump. BUT being a 150 GPH pump, you can only run up to 25 PSI before motor amperage becomes an issue.

I would suggest selling your pump to someone (Say with a VP-44 truck) and get the 90GPH@45 ADJ or 180GPH@45 ADJ HPFP. These are the pumps that can run pressure and volume.
