SOURCE: Transmission?

check the engine numbers if its the same engine then there is a good chance the box will fit but to be on the safe side check the gearbox number if that matchs then theres no problem yates210456

SOURCE: vacuum testing on Mercedes diesel 123 chassis not making sense

Everything on this vehicle is vacuum operated. going into the vehicle at the left rear of engine compartment there are color coded vac. lines-green a/c,yellow central locking,black shutoff diaphragm, clear source, yellow w/red stripe reservoir. any one of these could be a potential leak of vac. On diesel engines they have too high of compression to produce vac. so M.B. put a vac. pump on the front of the engine which is driven by your camshaft. Usually engine vac. changes rapidly with throttle position but because this vac. is not as easily controlled there is a separate control valve called a aneroid compensator that meters the vac. to your modulator on your transmission. It can be adjusted but it requires a special tool( basically it is a dial wheel that fits onto the post of the compensater). I would first make sure your rubber grommet is not torn on your modulator valve. If it is it will need to be replaced. If you remove that grommet you will see a metal plunger which can be grabbed with needle nose pliers and rotated to the left or right. I believe right is a firmer shift and left is a softer shift. stat by rotating approx. 1/2 turn to the left and see how the shifting feels. My first suggestion is to unplug the green and yellow vac. lines and see if the trans. shifts better. On your valve cover is a lever labeled off in case you lose vac. to the shutoff diaphragm. Become familiar with that lever so you can shutoff your engine in case you accidentally unplug the shutoff valve. you will probably find either your central locking or a/c system is the root of the problem.

4X4? it comes from the engine to a metal line mounted to the frame , passenger side. That line goes back to the transmission mount that another is connected to. that hose goes to the transfer case solenoid plug.

Fuel pressure 1998 jeep grand cherokee 4.0 L V6


You should have a test port on the Fuel Supply rail, use a tool from a local auto parts "Tool Loaner program" where you can borrow tools for free,w/a deposit of course,then follow the steps provided;

MPI Fuel System Pressure Test

The MPI fuel system used in vehicles equipped with a 4.OL engine employs a vacuum balanced pressure regulator. Fuel pressure should be approximately 55-69 kPa (8-10 psi) lower with the vacuum line attached to the regulator than with the vacuum line disconnected. System fuel should be 214 kPa (31 psi) with the vacuum line connected to the regulator and 269 kPa (39 psi) with the vacuum line disconnected. CAUTION: Some fuel may be discharged when connecting fuel gauge to fuel rail.
  1. Connect a 0-414 kPa (0-60 psi) fuel pressure gauge to test port pressure fitting on fuel rail (Fig. 7).
  2. Remove vacuum line from pressure regulator.
  3. Start the vehicle.
  4. Note gauge reading. With vacuum line disconnected, fuel pressure should be approximately 269 kPa (39 psi).
  5. Connect vacuum line to pressure regulator. Note gauge reading. Fuel pressure should be approximately 214 kPa (31 psi).
  6. If fuel pressure is not approximately 55-69 kPa (8-10 psi) higher with vacuum line removed from regulator, inspect pressure regulator vacuum line for leaks, kinks or blockage. CAUTION: Fuel pressure will rise to as much as 655 kPa (95 psi) when the fuel return tine is pinched shut, shut engine down immediately after pinching oft fuel return line.
  7. If fuel pressure is low, momentarily pinch shut the hose section of the fuel return line. If fuel pressure remains low, inspect the fuel supply line, fuel filter, and fuel rail inlet for blockage. If fuel pressure rises replace fuel pressure regulator.
  8. If fuel pressure is above specifications, inspect the fuel return line for kinks and blockage.

Capacity Test

  1. Remove the cap from the pressure test port in the fuel rail.
  2. Connect a 0-414 kPa (0-60 psi) fuel pressure gauge to the pressure fitting on the fuel rail (Fig. 7).
  3. Start the vehicle. Pressure should be approxi- mately 214 kPa (31 psi) with the vacuum hose connected to the pressure regulator and 269 kPa (39 psi) with the vacuum hose removed from the pressure regulator.
  4. If the pressure is not to specification, check the following before replacing the fuel pressure regulator:
  • 4a - Inspect the fuel supply and return lines/hoses for kinks or restricting bends
  • 4b - Check the fuel pump flow rate. A good fuel pump will deliver at least 1 liter of fuel per minute with the fuel return line pinched off. If the fuel pump does not pump adequately, then inspect the fuel system for a plugged fuel filter or fuel pump inlet filter (sock). Fuel pump flow rate can be done by connecting one end of an old A/C gauge hose to the fuel test port on the fuel rail and inserting the other end of the hose into a container of at least 1 liter capacity. Run the fuel pump by installing a jumper wire into diagnostic connector terminals D1-5 and D1-6. Be sure to pinch off the fuel return line or most of the fuel will be returned to the fuel tank.

Have a sarurn vue need to fine out where the vacum transmisdion jose goes


I'm guessing that you're talking about the engine end and not the transmission end. There should be a multi-line port (probably on the top of the intake manifold) with other vacuum lines attached to it, and there's also probably one port that has no line connected to it. Plug in the vacuum line from the transmission to that port. On the other hand, if you ARE talking about the transmission end, there should be a saucer-shaped disk about 1" - 2" in diameter with a port sticking out of it. The vacuum line from the intake manifold plugs onto that port. Good luck.

Loose vacuum line


That is probably just a vent hose for your gearbox or front differential. It doesn't need to be connected anywhere other than the gearbox.
