Cadillac Seville Fuel Rail
The Cadillac Seville Fuel Rail is responsible for carrying fuel from the pump to the injectors at a given pressure. During the early 1980s, for the throttle body injection models, the Fuel Rail was accommodated within a compact TBI unit. Consequently, the Fuel Rail had the provision for one or two injectors that were located over the throttle plates. This was similar to the position of carburetors. However, the design allowed the vehicle computer to actuate an internal solenoid. Subsequently, a metered spray occurs when the throttle opens. Subsequent generations, including present-day Cadillac varieties, have embraced multiport systems that come with a bolted external Fuel Rail along the intake runners. The individual port injectors are just upstream of each intake valve. A regulator ensures a consistent pressure so the control module can shorten or lengthen the pulse width for idle operation or heavy load. The updated forms of Seville are undergoing a transition to common rail-style direct injection. This is associated with a high-pressure Fuel Rail that exceeds 2,000 bar. Therefore, finer droplets will be directly injected into the combustion chamber for stronger power and lower use of fuel. Throughout all these stages, the differences relate to the pressure level, the placement of the injector, and how accurately the electronics time the delivery, but still, each Cadillac Seville Fuel Rail forms the backbone of the injection system.

Cadillac Seville Fuel Rail Parts Questions & Experts Answers
- Q: How to remove the Fuel Injector and Fuel Rail on Cadillac Seville?A:To remove the fuel rail and injectors, start by relieving the fuel system pressure and disconnecting the battery. Then, remove the intake manifold service cover and the air intake duct. On 1999 models, also remove the Throttle Body and gasket, as well as the throttle body spacer and spacer gasket. Disconnect the fuel supply and return lines from the fuel rail, and on 2005 and earlier models, disconnect the vacuum hose from the fuel pressure regulator. On 2000 and later models, disconnect the PCV fresh air tube. Remove the nut attaching the fuel rail end-point bracket retainer, and disconnect the electrical connectors from the fuel injectors. Remove the nuts securing the coolant pipes to the front fuel rail mounting studs, and then remove the fuel rail and injectors as a single assembly. To remove an injector from the fuel rail, flip up the U-clip retainer and pull out the injector. Finally, remove the old o-rings from the injectors. When installing the injectors, use new o-rings and, on 1999 models, a new gasket for the spacer. Tighten the spacer bolts to the specified torque. Installation is the reverse of removal, and be sure to check for fuel leaks after starting the engine.
