This is my second 2005 Chevrolet Impala, and it had the same exact problem as the first. The first cold weather day I started smelling gas in and around the car. Check under the hood, and sure enough, wet gasoline on and around the fuel pressure regulator. It seems that when they get 8-10 years old, the rubber 0-rings start to fail and first start leaking on cold days when the metal is cold and shrinks. After engine warmup, the leaking seems to stop, but leaks again when it's cold. The BWD Fuel Pressure Regulator replaces the OEM one perfectly, and out of 2 replaced so far on 2 different vehicles, seem to work fine. The OEM had no coating and was rusty on removal, while the BWD unit appears to be cad plated, and hopefully will not corrode as easily. Fitment is tight, but would be with any brand part. This was the least expensive, and only one stocked (Delco units would have to be specially ordered at my store), so this would seem to be the best bang for the buck. Only has a 1 year warranty, but if it makes it that far, it should last 8-10 years and 100k plus miles. Thanks to the guy who listed the 15/16 open end wrench and #30 Torx bit as tools required...

replaced the factory regulator as it was leaking into vacuum line. installed first bwd #23091 REGULATOR and within 2 hours car lost fuel pressure,thinking regulator couldnt be defective,i replaced fuel pump. still insufficient fuel pressure. warrantied regulator with another bwd unit,dropped 10psi of pressure, warrantied fuel pump,checked fuel lines for blockage,checked injectorsand fuel rail for leakage. finally re-installed original (but leaking) regulator and had adequate fuel pressure.warrantied out bwd unit and installed an ac delco unit and all is good. to make a long story short:2 defective borg warner fuel pressure regulators cost me 2 1/2 days of lost labpr time and almost cost me a customer. i have never had an issue with borg warner in the past BUT I WILL HAVE RESERVATIONS BEFORE USING THEM AGAIN !!!! the commericial guys at my store were very helpful with warranties and ordering my parts so BIG UPS TO NICK,JOE,BENS 1&2

    Comments about CARQUEST by BWD Fuel Pressure Regulator:

    Bought the Fuel Pressure Regulator by BWD (Carquest) for a 2002 Buick Century. Installed regulator and tested fuel pressure with key on, engine off. Pressure should read 52-59 PSI. With this regulator, pressure reading was only 46 PSI. Tried bleeding system with multiple circulations of key on/off to prime system. I will be returning this product and looking elsewhere for an adequate replacement. My advice is to ensure you verify system pressure reading prior to running engine and putting everything back together.

    Comments about CARQUEST by BWD Fuel Pressure Regulator:

    Purchased because my current BWD replacement was showing 44PSI when the specifications are between 52-59PSI. I verified the fuel pump was good by blocking the return line and testing which showed 65 PSI from the pump. My first replacement showed 46 PSI which was a 2 PSI gain from the one I was replacing, the 2nd showed 44 PSI. I am going to return and buy an OEM one.

      Comments about CARQUEST by BWD Fuel Pressure Regulator:

      Product works as described. Replacement is fairly straightforward on a GM engine. There are plenty of youtube videos to describe how to replace. you will either need a 24mm or 13/16 wrench or crescent wrench to remove the retaining nut on a GM 3.4 V6. be sure to place rags/paper towels etc under the fpr before disconnecting as you will leak fuel. i also add a dab of white lithium grease to the o-ring to ease insertion into the fuel rail. overall, a good part and time will tell if it will hold up.

            once you have it out. change the bolt "screw" use different head. Original design is bad using T-30. took 1.5 hours instead of 10 minutes job. had to use a hacksaw then grind the screw out. they should provide a hex head ex. 10mm screw with new part. part itself is great so far. No fuel smell in van anymore and seems more power.

              Comments about CARQUEST by BWD Fuel Pressure Regulator:

              Replaced the OE fuel pressure reguator because it was leaking. Installed a BWD regulator and the engine barely ran! The engine sputtered and hesatated and the car didn't go over 10 MPH. I put the original unit back in and the car ran great (despite the OE unit leaking). I exchanged the BWD unit with an A C Delco and the car ran great with no gas leaking. I read other reviews on this website from customers who bought the same BWD unit and had the same problem. I'm glad I wasn't alone with the problem being the BWD unit as the cause of the problem.

                Will a bad fuel pressure regulator cause an odor of gasoline when you first start the vehicle, and perhaps make the engine turn over longer before it starts?

                  A:

                  Sometimes when it begins to go out, the engine will sound like it is misfiring. This can be a slight chug or missing a beat in the circulation of the plugs. Because a malfunctioning regulator can cause the plugs to foul fast and frequently, this will eventually be one of the symptoms. Some cars will have a hesitation at take off. An engine will seem to hiccup then all will be fine. In a few cars the hesitation will happen lightly at first then it’ll start to grow larger or it will be enough to make it stall.
