GlowShift HPOP Gauges are made specifically for the 6.0L Power Stroke and 7.3L Power Stroke. This high pressure oil pump gauge monitors the high pressure that enters into your Ford truck diesel engine’s oil pumps, reading levels from 0 to 4,000 PSI with unrivaled accuracy. Having a weak or defective HPOP could starve the injectors for fuel and lead to other fuel system failures. This gauge will keep you alerted in the event levels aren’t where they should be. Each HPOP gauge kit comes with parts for installation including wiring harnesses, mounting hardware and more.
