Kirban Fuel Pressure Regulator Billet Adjustable 5.0L/5.8L 1986-1993

Product Description

Kirban Adjustable Billet Fuel Pressure Regulator for 1986-1993 5.0L and 1987-1993 5.8L Ford Mustangs.

This billet style adjustable fuel regulator has been one of the most popular regulators in the Ford marketplace since its introduction in the mid-1990s.

One of the key features is the fact it closely resembles the factory fuel pressure regulator in format and size. This design enables it to work with almost every different aftermarket intake available for the popular 5.0 Mustangs.

The entire unit is 100% brand new and 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.

We are proud to say this entire adjustable fuel regulator has always been 100% Made in the U.S.A. and by the same supplier.

With its great price structure and sales of over 25,000 in the last 15 years, it's easy to see why this is the regulator many Mustang owners want for their application.

An excellent upgraded adjustable fuel regulator to enhance your Mustang's performance.

*Fits 5.8L from 1987-1993.

Does this have a port for a gauge?

Asked by: E3650
No it doesn't, if you are using the stock fuel lines you could use the shrader valve port located by the front of the passenger side valve cover.
