The Billet Adjustable Fuel Regulator (86-93) has been DISCONTINUED....Please see our other for an updated selection.
This Kirban Performance fuel pressure regulator is fully adjustable from 30-100 psi. It is made from all new parts and has two O-rings internally, so it will never leak. Any adjustments can easily be made without removing the vacuum line since the adjustment is a separate port on the top.
Fits 86-93 Mustang 5.0 and 87-93 5.8
