Cracked rubber hoses, leaking injection valves and a tired temperature sensor often cause rough idle, hard hot-starting and a fuel smell on the injected B23F engine. This category gathers the parts that keep fuel delivery tight and metering accurate on the 2.3-liter four-cylinder 240.

The group includes injection valves, fuel hoses and hoses in various dimensions, gasket sets, a temperature sensor as well as smaller fasteners such as washers, screws and rubber bushings. During a rebuild it is common to replace the whole hose package and the seals at the same time – old rubber turns hard and brittle, and a leak on the pressure side shows up both as poor cold-starting and as an odor in the engine bay. The temperature sensor is a typical troubleshooting point when the engine runs rich or lean with no obvious cause.
Because these parts are tied to the fuel injection on the B23F specifically, it pays to check the connections and dimensions against your engine before replacement.
