Delphi Fuel Injection Pressure Regulator P/N:FP10527
Delphi FP10683 fuel injection pressure regulator for the 2010-2022 Toyota 4Runner and other vehicles keeps fuel pressure steady in the fuel system.
A worn regulator can show up as rough running, hard starting or a fuel smell. Those signs alone don't prove the regulator is at fault, since a clogged fuel filter is another common source. These applications call for a single regulator.
This regulator is a direct-fit replacement for the 2010-2022 Toyota 4Runner, the 2012-2014 Toyota Tundra V6 4.0L and the 2010-2014 Toyota FJ Cruiser V6 4.0L.
