Do you own a 1986-1993 5.0L or 5.8L Mustang? Now you can regulate fuel pressure using one of the most popular regulators in the Ford marketplace since its introduction in the mid-1990s. That regulator is this Kirban Adjustable Billet Fuel Pressure Regulator from CJ Pony Parts! This regulator's design enables it to work with almost every different aftermarket intake available for the popular 5.0 Mustangs.

Features and Benefits:
- Two (2) internal O-rings prevent leaks
- Easy to adjust without removing the vaacum
- Adjusts from 30-100 psi
- Provides 30% more fuel flow
- Delivers up to 75 pounds of pressure
- 3-bolt mounting format
- Includes hardware to attach to fuel rail

This Kirban Adjustable Billet Fuel Pressure Regulator has two O-rings internally, so it will never leak. Adjustments can easily be made without removing the vacuum line, since the adjustment screw is a separate part on the top. This adjustable fuel regulator is totally adjustable from 30-100 psi. It has a larger feed and return fittings internally for 30% more fuel flow, which reduces fuel restriction of the fuel regulator. If necessary, the regulator can easily be rebuilt as we stock the diaphragms separately.

This regulator can not only deliver 75 pounds of pressure, but it can also be set below stock fuel pressure if the car runs fatter injectors. The 3-bolt mounting format can also be used in several other Ford applications besides the ones noted above. Ford basically used either a 2-bolt mounting or a 3-bolt mounting design during the 1980s and 1990s on their fuel rails. The fuel pressure regulator comes with new hardware to attach it to the stock fuel rail.

*Fits 5.8L from 1987-1993.
