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 94-95 Mustang 5.0, 94-96 5.8, 96-97 4.6 (2V & 4V), 98 (4V), and 94-98 3.8
