the red top facet i have may only flow 37gallon per hour, or 168 LPH, however my injectors only flow 151.1LPH (4xsiemens deka IV 630cc), so perfect for my needs at standard pressure.
at higher static pressure of 6BAR (900cc equivalent) i will need 216LPH, so would be inadequate for that.
at standard pressure it would be close to 500bhp though, so as a lift pump is absolutely fine as injectors don't run at max flow for long.
