Helpful Notes

• Supply matters: A healthy lift pump and clean filtration help protect the P7100 and stabilize fuel pressure under load.
• Measure pressure: Add a dedicated fuel pressure gauge when upgrading pumps or OFVs; follow the pump maker’s pressure guidance.
• Component pairing: Higher-output injectors and delivery valves may require turbo/exhaust and transmission upgrades to keep EGT and drivability in check.
• Tank pickup: Draw straws or sumps can reduce starvation on big-flow systems—use proper sealing and routing.
• Professional work: Internal P7100 mods (springs, DVs) should be installed and calibrated by qualified technicians.

Frequently Asked Questions

FASS vs. AirDog—what’s right for my 12-valve?

Both are proven. Choose a FASS Titanium for integrated filtration and steady supply, or an AirDog II-5G for high-flow builds; size to power goals.

Should I run an adjustable overflow valve?

An adjustable unit like the Tork Tek OFV010 can help fine-tune return pressure; verify with a gauge and follow pump specs.

What’s the difference between 191 and “full-cut” delivery valves?

191s are a common street upgrade; full-cuts provide maximum fueling and are typically for race use with supporting mods.

Do I need a fuel pressure gauge?

Yes—monitoring supply pressure is critical for P7100 health and tuning. See Gauges / Related for fuel pressure kits and tees.

My truck won’t shut off—what should I check?

The P7100 shutoff solenoid can fail. Replace it with the CPP solenoid or add a manual shutoff cable kit.
