Key Features & Benefits – MGP AN6 fuel pressure regulator kit
The MGP AN6 fuel pressure regulator kit is a universal set for EFI fuel systems, intended to help with fuel pressure setup and monitoring. The kit is built around Dash 6 (AN6) connections for inlet, outlet and return.
It includes an adjustable fuel pressure regulator with a bracket and a vacuum port, plus a 2" pressure gauge. Vacuum compensation supports more consistent pressure behaviour as load changes, which can be relevant for both naturally aspirated and turbocharged setups.
When is this useful?
It is useful when you want to adjust and check fuel pressure in an AN6-plumbed EFI system, and you want a kit that also includes the basic hose and fittings for installation.

Selection & installation tips
- System check: Confirm your vehicle is EFI and you have a return line or a return-style layout in your fuel system.
- AN6 compatibility: Verify your rails/distribution block and hose ends are truly AN6 (Dash 6) and the thread/sealing system matches.
- Vacuum port routing: Use a stable manifold vacuum source and keep the vacuum hose short and kink-free.
- Placement: Mount it so the gauge is readable and the regulator is accessible for adjustment, while hoses are not under tension.
- Fuel compatibility: If long-term E85 use is planned, a different solution may fit that requirement better.
Before installation, verify AN6 fitting type, return-line layout, and vacuum source, then match them to the specs above for a correct, tidy setup.
