Before starting work on Honda models from 2005 and Acura models from 2003, drain the fuel pressure. Take the wire connection off the car's negative battery terminal. Take out the fuel pump/fuel level sender from the fuel tank and put it on your workbench to clean. Pull out the fuel level sending unit plug and then pull it off from the fuel filter housing. To take apart the fuel pump/fuel filter housing, disconnect the fuel supply line with a new O-ring and remove the case. Unplug the power wires for the fuel pump from its circuitry, and disconnect the pump's grounding wire from the housing's fuel filter unit. Open the
Fuel Pressure Regulator housing by unscrewing two small latches. Next, remove the metal strap connecting the fuel pump to the housing. Before reinstalling, take off the part that holds the pressure regulator, push the regulator out of its housing, and discard the worn O-rings, which need replacing. Look at the spacer and filter screen, and get new ones if you see any damage. Take out the fuel pump by unhooking two locking parts and pulling it through its housing, throwing away the rubber O-ring inside. The pump needs a new O-ring for reinstallation. Take off the clip holding the fuel pump suction filter, and pull out the filter itself. Scrub the fuel strainer clean with fresh solvent, or buy new parts if the cleaner isn't doing the job. Putting the components back in place needs fresh O-rings and a fresh retainer clip installed on the strainer. After putting the pump back in, reconnect the ground cable, turn on the engine, and look for gas leaks where the pump fuel hoses connect. First, inspect the gas lines for any dripping. When everything looks good, put back the access cover, carpets, and rear car seat.
