This part you describe is the fuel pressure regulator. If your car is working well, and you have a leak hear , you may only need a seal or gasket. GOOD LUCK FRIEND.

Testimonial: "Thanks for your response. I don't believe this is a fuel pressure regulator. According to the Haynes manual I have the fuel pressure regulator is in the tank as part of the fuel pump module. This is a returnless system, meaning there is no line going to the tank to return excess fuel from a regulator. The pressure is bled off in the tank by the regulator. I found a diagram of the fuel rail here. http://www.moparpartsoverstock.com/showAssembly.aspx?ukey_assembly=904556&ukey_make=1095&ukey_model=15980&modelYear=2001&ukey_category=23324&ukey_driveLine=8976&ukey_trimLevel=20251 It does not show the "hat" part that's on my fuel rail. Everything else is identical."

SOURCE: How to replace a water pump on a 1999 dodge

so i just replaced my water pump today on the same car, mine is a 5.9 magnum. I drained the whole system before i started working on it, next you have to take off the fan, if you look on the inner side of the fan there is a big nut there, in order to loosen that i put to bolts into the holes on the water pump pulley and used a thin screwdriver for leverage, while putting pressure on that, i loosened the nut, be careful not to slip cuz those fan blades are dangerous. but once you have removed that nut from the pulley take out the four bolts holding on the housing, pull the fan and the housing out at the same time. next remove the belt, after that is done, disconnect the hoses from the water pump, there are three, one on each side and one on top. there are a total of eight bolts holding the pump on, keep track of them because they are different sizes. But that is how i removed mine. It was all farely simple i am a girl and i managed to do it so i think you should be fine. Hope it works for you becuase it didnt work for me, i now think that it is my head leaking, if you know anything about that let me know.

SOURCE: Fuel injectors leak at fuel rail

Get some new O-rings, and this time put oil on them before you insert them into the fuel rail. The regulator is alright.The problem is that the o-rings can roll up, or twist when push em in dry. Had this problem once, easy fix, but was frustrating.

Fuel line location?


You did not mention type of vehicle but will give a general answer. If older vehicle with carb then fuel line comes from fuel pump right on engine and goes into carb with a fairly large metal line. On anything newer there are several lines because fuel injection requires constant high pressure in system. So fuel is pumped from a pump located in tank all the way through large line down length of car to fuel rail under hood. The fuel rail has a pressure regulator and whatever fuel is not needed is pumped back to tank in second line. These lines run together all the way from tank and are fairly large diameter. Bigger than brake lines. So look for two lines coming under vehicle to top of engine.

2001 Chevy s10 4.3 surges and won't pick up speed. Valves rattle when you mash accelerator to the floor and it smells like its flooding out


You want to start with the knock sensor, located on the side of the block, about 1 1/4 inches in diameter, 1 1/2 inches long. funny looking sensor. It is suposed to pick up knocks/pings in the engine and tells the ECM to advance or ****** the engine. Check the engine for codes, even if the light is not on. Let me know we can go from there

Gas Leak under Hood on 2004 Aviator


It can only be a small area. Does it seem to be coming from the fuel rail area, which is usually chrome color. The fuel pressure regulator or fuel line. The fuel line come up the driver side firewall connects to a regulator, and then feeds into the fuel rail. Any of these connections could be the leaking source. Also one of the rubber o rings for the injector could be leaking. Look to see where it mostly looks to be coming from and feel around the pipes for the gas.

It's common for the fuel pressure regulator has gone bad and will need to be replaced. It take's about 15 min to replace with common tools, if there is an Auto Zone around your area. You can buy the fuel pressure regulator there and that can give you the step bu step instructions to get the job done with common tools, just make sure you oil the O-rings to the regulator before installing it back to the fuel injector rails. The fuel pressure regulator is on the fuel injector rail buy the throttle body, you can see it. It looks like a cylinder about an inch in diameter and 1 1/2 inches long with a vacuum tube connected to it. Inspect it for any signs of fuel leak. Good luck and keep me posted.
