FITMENT:
- Universal, any electronic fuel injected engine with a return style fuel system with port or throttle body injection.
- May be used with direct injection vehicles to regulate fuel pressure to the inlet of the high pressure fuel pump.
- May be used for inline or deadhead regulation
- May be used in a series with another F1i, F2i, or F4i to supply multiple pressures and/or reference strategies with one feed line

- Hydrodynamic internal cavity suitable for passthrough regulation
- Zero chatter design for maximum life expectancy and maintained accuracy
- Fine Pitch adjustment screw for precise setting of fuel pressure
- Reversible stainless steel mounting bracket included
What is the key advantage of the F4i over the F2i
- Some installations may be simplified with F4i. Despite the higher cost of the F4i, the four pressure ports may eliminate y-blocks and associated fittings/hose/hose ends...which may lead to a faster, cleaner, and/or less expensive installation
