FAQ
Does this kit replace the factory in-tank lift pump?Yes. The included Fuel Module Upgrade Kit pulls through a bulkhead fitting and bypasses the weak OEM in-tank lift pump for consistent supply under load.
What fuel pressure does the II-5G run? The integrated diaphragm regulator is adjustable and can be boost-referenced. Typical preset for Cummins common-rail applications is in the mid-teens (psi); always verify with a gauge.
Do I need tuning for this pump? No tuning is required. This system improves supply side delivery and filtration; it does not alter ECU calibration.
Which filters should I stock for maintenance? Use FF100-2 (2-micron fuel) and WS100 (water separator). Replace per service interval or sooner in harsh conditions.
