Quick facts
- Part: Standard Ignition PR381 fuel injection pressure regulator
- Fits: 2006 Honda Civic 4-cylinder 1.8L
- Condition: New
A failing regulator can show up as hard starting, a rough idle or a fuel smell. Before replacing it, find the cause: with the engine off and cool, look for fuel seepage around the regulator and its O-ring. Pressure tests need the engine running or a gauge on the fuel line, so leave those to a shop.
Fits
It is a direct-fit replacement for the 2006 Honda Civic 4-cylinder 1.8L, engineered around the fuel system requirements of Honda engines. This engine takes one regulator.
