Fuel Pressure Regulator Installation




Written by: racer5e


First of all you have to make sure you have all your Itemís needed. Here is a list of everything you will need:

 Adjustable fuel pressure regulator 
            Fuel pressure gauge            
                Fuel rail adaptor                
  4 feet of 1/4 in. (6.4mm) fuel line  
               Fuel line clamps               
 1 ft. of 1/8 in. (3.2mm) vacuum hose 


Once you are sure you have everything we can begin.



Youíll first start of by disconnecting the negative terminal form the battery with a 10mm wrench or socket. Then open your gas tank to release the pressure. Once youíve done that we can begin with installation of your new fuel pressure regulator.

Now youíll want to disconnect the fuel hose form the return line. Itís right behind the transmission (gear box). Be ready with a rag or cloth to clean any liquid that may come out.





Next, disconnect the vacuum line on the stock fuel pressure regulator. With a 10mm socket unbolt the regulator.







There is one more bolt to remove and itís on the other side of the fuel rail.





You should have this once itís off.





Now install your fuel rail adaptor. You can use your existing O-ring or you could buy a new one, which is recommended.





Now find were your going to mount your regulator.





Now measure your fuel hose to the retune line and cut. At the same time measure and cut your vacuum hose. Now install. On the fuel pressure regulator, make sure you connect the return line to the OUTPUT.





Now install your gauge and hose to the fuel rail.





The installation is finished. Now close your gas tank and reconnect your battery. Turn on you car and look for any leaks. If any are found, shut engine off on make sure you have tightened your clamps right.



Now its time to set the fuel pressure! Turn on your car once more. Now go take a look at your fuel pressure gauge. Some people do this next step with the vacuum hose off, and some do it with it on. You choose. I did mine with it on. On top of the new regulator there will be a bolt with a nut. Loosen the nut and turn the bolt clockwise to raise the pressure to the desire setting. Once youíve achieve the desired pressure turn the nut clockwise to tighten.







I set mine at 45psi (3.1 Bar) because that the recommended pressure to run 14.5psi (1 Bar) of boost safely.





There are many different types of regulators so yourís may not look like this. This is just a guide to help you install your new rising rate fuel pressure regulator.
