Question about 1990 Jeep Wagoneer Limited

1 Answer

Fuel leaking Hi, I drive a 1989 jeep wagoneer limited and it recently began to leak fuel from the steel tubing and what looks like a filter located on top of the engine just back from the main fan belt. It looks like fuel is seeping, fast from the seam of the steel tubing and the filter thing or whatever it is, any ideas on a quick fix so I can get to a garage tomorrow without blowing up. Thanks in adavance, Rob

    Thank you. It is 4.0L - 6cyl and the high pressure fuel line (rubber seal) totally worked because the leak was on the seam b/w the reg and the line. Good karma coming your way amigo, much appreciated.

If it's a 4.0 engine, the filter thing is the fuel pressure regulator (does it have a vacuum hose going to a fitting on the intake manifold?) Depending upon how much material (clean tubing) you have to work with the temporary"fix" is just about the same as the real repair. Cut the line, removing the failed part, and install a new piece of steel tubing, using crimp type unions (they have brass ferrules on both ends that seal permanently to tubing once they are tightened. Sometimes you need to remove a decent length to get to a straight clean area (unions are not recommended to be used on curved sections of tubing.
Or, if you can't do this, cut the tubing right over the leak, slip a piece of high pressure fuel line (rubber) over both ends and fasten with two clamps (made for fuel lines, not for water hose applications) Make sure that rubber hose extends at least one inch past the leaking area.That will get you to a shop! Check the regulator. it's doubtful that both the line and reg are leaking.
Good luck

Jeep wont hardley idle ..when speed gets up to about 30mi. it runs great. about six months we replaced distributor, s.p.wires, s.plugs, fuel filter, fuel pump, air filter, some vacuum hoses. been fine...


Sounds like a possibility of a vacuum leak. Inspect the vacuum tubing for damage or wear or just not being connected. One mechanic's trick is to spray carburetor cleaner on the vacuum lines with the engine running. Use safety goggles when trying this. If there is a vacuum leak - when the carb cleaner hits it the engine will speed up.

Where is fuel filter on 1998 Volvo S70 non turbo?


The fuel filter can be located under the carpeted cargo storage floor at the rear of the wagon. Remove the four 10mm bolts, remove the cover. You will then see a removable plate to the right just behind the rear passenger seat. Fuel filter can be seen through hole in hole. Replaced from underneath wagon. Be sure to make sure lines are fully inserted onto filter. Check for leaks. Note arrow on filter for correct fuel flow. Good luck and hope this helps and no smoking please LOL

1990 Jeep grand Wagoneer i ran out of gas,when i put gas in in the jeep the truck try to start but start draging then just did nothing,i try to jump it and steel nothing but just a clicking sound


by running out any debris in your tank will get sucked into your fuel pump. REplacing the fuel pump usually means removing the tank. You can try replacing the fuel filter first its much easier and cheaper. The filter is attached to your fuel line between the tank and the engine, usually in the frame. TAkes about 15 minutes to replace.

1989 jeep wagoneer will not crank. Motor turns over and there is fire on the plugs. changed the fuel pump and filter. (Pump was bad) Fuel delivery is not right.


replace the crankshaft poisition sensor at the bell housing on drivers side, must be done from under the truck, very hard to see and even harder to replace, but that will be the problem..

89 Wagoneer drives rough


The thing to do now is a fuel pressure test pump could be weak just a few pounds under the recamended pressure will do that weather its mechanical or electrical . Is there a filter in the carb. wear fuel fine hooks? If none of this is an issue at least you can eliminate fuel deliverly as the problem.

Fuel Filter seems like it's attached, but leaks.


De-pressurize the fuel system. (un-plug the fuel pump wire or fuse and crank the engine a bit) Remove the fuel filter and check on the fuel filter tubes and inside the connectors for the "O" rings. They can become damaged during removal and this usually causes the leak. Additionally, check the new filter itself for any damage.

1989 jeep grand wagoneer--no gas getting to carb.--


That may be right - no gas in the carb is likely a bad fuel pump, or a clogged fuel filter.
