Product Overview
A return-style EFI build needs a regulator that can set base pressure and send excess fuel back to the tank. This AN6 kit is for custom plumbing and tuning, not a bolt-on cure for an unknown factory fuel-pressure problem.
The regulator meters excess fuel back to the tank to maintain chosen rail pressure. It is a fabrication and tuning part, not a drop-in repair for every factory system.

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Confirm fuel type, pump flow, required pressure, fitting thread, return-line size, and whether the vehicle is factory returnless.
Frequently Asked Questions
Q: Does a 160 PSI gauge mean the regulator controls 160 PSI? A: No. Gauge range is not the regulator safe operating limit.
Q: Can it replace a returnless regulator directly? A: Usually not; conversion plumbing and tuning may be required.
Q: Why can pressure rise with boost? A: A boost-referenced regulator maintains injector differential pressure when designed for it.
Q: Is sealant used on AN flare seats? A: AN flares seal at the flare, not the thread.
