Fuel Pressure Release

WARNING: This page is about a different car, the 2004 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.

Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.

NOTE: Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel pressure cannot be completely released because B 15 models do not have fuel return system.
