    similar, but it is a pin-hole leak in the hose about an inch before the elbow to the o-ring. Again, how hard is this to replace?

    i have a fuel leak at the quick connect fitting at the rear rail. Do I replace the whole line or is there another solution?

Unscrew it and replace the "O" ring at the fitting. These "O" rings like to get old and crack.

1993 dodge dinesty 3.4 fuel rail leaks how can i repair


If the metal fuel rail itself has a leak, it should be replaced. If it is leaking by an injector, the O-rings on the injectors need to be checked and probably replaced. If a fuel line to the rail is leaking, that will have to be repaired. There will be two fuel lines at the rail, the feed line in from the gas tank, and a return line from the rail back to the tank. If there is a pressure regulator on the fuel rail (it will have a short vacuum line hose to it), the regulator may also have an o-ring to keep from leaking where it mounts.

Fuel injector reeplacement


you don`t say what motor is in this so here is a basic procedure, find the fuel rail where the fuel lines connect to at the intake manifold.disconnect the fuel lines(be carefull you could get gas in your eyes from fuel spray or start a fire due to hot engine)these lines have high pressure fuel in them.look at the fuel rails to see what all is in the way to remove them and remove interferance items.remove the bolts that hold the rails to the intake manifold,gently lift wiggle the fuel rails and you may have to pry up on the rails in places to get them to come out with the injectors attached the rails.you should make sure any debris is removed from around the injectors so no dirt falls into the injector holes before you remove.then you can remove the injector to rail lock clips and remove the injectors from the rails.clean areas were the injectors will be going apply either gas or silicone on the injector O rings then install injectors to rail install lock clips and reassemble.replace all the O rings as they get dried out brittle and crack or split.re-install removed components start car and check for fuel leaks.

Gas line leaking by engine how do repair that?


Where is it leaking? If its at the fuel rail fuel pressure regulator you may need a new regulator if leaking on the metal part. If its leaking at the rail side its just the "O" ring. Relieve fuel pressure(push in valve under plastic cap right side beside alternator on rail. Remove the torx screw holding regulator bracket. Pry out and replace "O" ring, reassemble. If its not the regulator it may be a fuel injector, you need to remove the fuel rail and replace both the upper and lower injector "O" rings. This however needs the intake manifold removed to repair.

  1. Before servicing the vehicle, please familiarize yourself with safety procedures.
  2. Disconnect the negative battery cable.
    CAUTION The engine appearance cover is equipped with a noise suppressor. If the noise suppressor becomes separated from the engine appearance cover it must be positioned on the intake manifold prior to installing the engine appearance cover.
  3. Remove the engine appearance cover and the noise suppressor, if detached.
  4. Remove the air cleaner outlet pipe.
  5. Release the fuel system pressure.
  6. Remove the four engine appearance cover mounting bracket nuts and the brackets.

Removal & Installation

8205896.gif
Exploded view of the fuel rail and injector mounting


Take care when servicing the fuel rail assembly to prevent dirt or contaminants from entering the fuel system. ALL openings in the fuel lines and passages should be capped or plugged while disconnected.
  1. Before disassembly, clean the fuel rail assembly with a spray type cleaner such as AC Delco® X-30A, or equivalent. After removal, DO NOT immerse the fuel rail in liquid solvent.
  2. Properly relieve the fuel system pressure and disconnect the negative battery cable.
  3. Remove the air intake duct, as necessary for access.
  4. Tag and disengage the fuel injector electrical connectors.
  5. Disengage the fuel pressure regulator vacuum line, then tag and disengage all other necessary vacuum hoses.
  6. Loosen and remove the fuel rail retaining bolts.
  7. If necessary to remove the fuel rail assembly completely from the engine compartment, or to prevent stressing and damaging the fuel lines, disconnect the fuel lines from the rail assembly.
  8. Carefully lift the fuel rail assembly and fuel injectors from the intake.
  9. Carefully release and separate the fuel injectors from the rail assembly.
  10. Remove and discard ALL old O-rings from the fuel injectors and, if disconnected, the fuel lines.
To install:
  1. Lightly coat the new O-rings with clean engine oil, then position them to the injectors and, if applicable, fuel fittings.
  2. Install the injectors to the fuel rail assembly.
  3. Carefully install the fuel rail and injectors to the intake manifold. Make sure the injectors are properly seated in their bores, but DO NOT force them into position.
  4. Install and tighten the rail retaining bolts to 62 inch lbs. (7 Nm).
  5. If removed, connect the fuel lines to the rail assembly and secure the fittings.
  6. Engage the fuel pressure regulator and any other vacuum lines, as noted during removal.
  7. Engage the injector electrical connectors.
  8. Connect the negative battery cable and cycle the ignition switch (without attempting to start the engine) in order to pressurize the fuel system, then check for leaks.
  9. Install the air intake duct.

After removing the fuel injectors and rail to remove the manifold, how do you reinstall the fuel injectors?


the same way you took it apart. put a little grease around the rubber seals so they will slide in easier. just tap on the fuel rail while lightly tapping it into place.

P0172 AND P0174 FORD F150 1998


Basically this means that an oxygen sensors
in bank 1 and bank 2 detected a rich condition (too little oxygen in the exhaust).

A code P0172 and P0174 may mean that one or more of the following has happened:
1. The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
2. There could be a vacuum leak.
3. There could be a fuel pressure or delivery problem

Possible solutions include:
Inspect all vacuum and PCV hoses, replace if necessary
Clean the MAF sensor. Consult your service manual for its location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
Inspect fuel lines for cracks, leaks, or pinches
Check the fuel pressure at the fuel rail
Check the fuel injectors, they may be dirty. Use fuel injector cleaner or get them professionally cleaned/replaced.
Check for an exhaust leak before the first oxygen sensor (this is unlikely to cause the problem, but it is possible)

Fuel injecter locations , one or two need to be replaced,1996 pontiac sunbird 4 cylinder


The injectors on the vehicle are going to be located on the rear side of the engine along the base of the intake. Find the fuel line coming up to the engine from the bottom of the car and follow it until you see where it connects to a metal line. Follow the metal line until you find the first injector and then follow it until you find the rest of them. Disconnect the battery, unbolt the fuel rail, unplug the injectors, remove the rail with injectors and replace the injectors and put back together.
