Standard Ignition Fuel Injection Pressure Regulator P/N:PR88
Standard Ignition PR593 fuel pressure regulator for the 2009-2019 Toyota Tundra V8 5.7L and other vehicles holds fuel pressure steady in the fuel system. It helps keep fuel delivery consistent and precise for smoother operation.
Hard starting, rough running or a fuel smell can be signs of a failing regulator. These signs alone do not prove the regulator is the problem, since a clogged fuel filter can cause them too.
It fits the 2009-2019 Toyota Tundra V8 5.7L and the 2009-2018 Toyota Sequoia V8 5.7L. Each engine takes a single regulator.
