Lift Pump Fuel Pressure Monitoring/Monitor

boonhauler said:

I recently had a lift pump go out on me stranding me in the middle of nowhere. I've decided to install a Fleece PowerFlow lift pump hoping that it's more reliable than a run-of-the-mill aftermarket pump.

I'd like to monitor my lift pump fuel pressure. I have a Smarty Touch installed but there's no PID for fuel pressure.

Just wondering if any of you guys have any idea on how I could accomplish this monitoring.

As always, thanks in advance,

Carl

back in the day my employer retrofitted some of our 24 Valve Bluebirds with a low fuel pressure warning light..
basically it amounted to a 12 psi pressure switch in the supply side after the primary filter and a red warning light on the dash and a few feet of wire.

There are some low psi kits out there and it’s easy enough to make your own, but they aren’t really that useful on a HPCR. The CP3 is rated for -5 psi to + 15 psi inlet pressure. The OEM pump moves 90 GPH+ at 0 psi, so plenty of flow for the CP3. It’s not uncommon to pull the OEM lift pump down to ~3 psi under full load on a tuned motor, maybe even a little lower depending on filter status.

So what pressure would you run on a HPCR? I never came up with a good one with a readily available switch, so a pressure gauge went in over a pressure light.
