im useing the 1.8 zetec efi inlet,
i do understand the pressure system is just
the engine is finished as built it all myself, just the regulator i need now,
i orded a cosworth one but dident know about the o-ring connection, as my custom fuel rail does not have the o-ring connection to house the regulator.

can i ask whats wrong with that adjustable fuel pressure regulator above? as was told these are good regulators?
