2003-2009 Toyota 4Runner Fuel System Parts

Fuel delivery on the fourth-gen 4Runner is something most owners don't think about until a symptom forces the conversation — a stumble under hard acceleration, an intermittent no-start, or a hesitation at highway merge speed that the ignition system keeps getting blamed for. The fuel pumps, injectors, and pressure regulators that keep the 1GR-FE running cleanly are what 2003-2009 Toyota 4Runner Fuel System Parts cover.

 

Preventive fuel pump replacement on a high-mileage fourth-gen is the maintenance call that owners who have been stranded on a remote trail with a failed pump make without hesitation afterward. The pump lives in the tank and access on the fourth-gen comes from behind the rear seat, not from dropping the tank — which makes the job approachable for any owner comfortable with basic fuel system work and means a pump that is starting to weaken has no excuse to stay in service past the service window.
