• Q: How to Service and Repair a Fuel Pressure Regulator on 2001 Toyota Tundra?

  A: Service of the Fuel Pressure Regulator requires removing first the air cleaner hose followed by the intake air connector while disconnected fuel return hose that must keep a shop rag below the regulator. The procedure starts with unbolted the engine wire from the LH cylinder head cover while disconnecting the protector from its bracket on the RH cylinder head cover through wire lifting. Use proper caution when pulling out the pressure regulator after removing its two bolts because you must take out the O-ring. When installing the pressure regulator attach a new O-ring to it by applying a small amount of gasoline followed by fitting the regulator to the LH delivery pipe. Perform this installation step only if the regulator moves easily or else repeat the previous procedure. Attach the pressure regulator with two bolts which require 8 N.m (80 kgf.cm, 71 in.lbf) torque before installing the engine wire and its bolt. Secure the fuel return hose against the fuel pressure regulator until the stopper is reached and use a hose clip to retain it. The last steps include installing the intake air connector and the air cleaner hose then verifying fuel leakages.
