Hold fuel-rail pressure steady across throttle changes with the Standard Ignition Fuel Injection Pressure Regulator PR73. It installs as a direct-fit replacement for the listed Volkswagen applications: the 1993 and 1995 Golf (L4-1.8L); the 1986-1991 (H4-2.1L), 1992-1993 (L5-2.5L) and 1994 (L5-2.4L) Transporter; and the 1983-1985 (H4-1.9L) and 1986-1991 (H4-2.1L) Vanagon.
- Regulator function: controls fuel flow on this gas system to maintain a consistent supply pressure, rated at a 37 psi operating pressure, so the injectors stay fed.
- Validation tested: the manufacturer's process includes 200+ hours of vibration testing, 1000+ hours of extreme heat and cold operational testing, and on-vehicle testing.
- Durable build: made from corrosion-resistant, high-durability materials intended to resist wear and deformation through prolonged use.
- Details: straight nipple orientation; ships with a caution sheet.
A fuel pressure regulator manages the pressure delivered to the injection system; signs it may need replacing include hard starting, rough idle, or a fuel odor. Diagnose the cause first, and if a failed regulator is the cause, this unit replaces it. The listed applications use one per vehicle. Country of origin: Mexico.
