had the same trouble on my 90.look carefully at the fuel lines that come up the front of the motor.i had a slight drip where the lines go into the fuel rail.

thanks for the reply,tried that already ...no luck. think i have a problem with he controle module under the dash.it takes the signal from the head and open and closes the proper vent/door by vacumm. was hoping someone has been there already.not much fun getting under the dash,and the sevive...

had gas smell while driving and while parked.two steel fuel lines come up front, motor pass side.there is an o-ring that can leak .hard to see. mine was after that where it goes to the left side fuel rail and to the fuel regulater.it pulls right out of the regulater,but mine was leaking at the...

wish i could send you a picture of what i mean. thanks fo the response but the line mean is on top of the motorpassed the point where they thread together.it`s going into the fuel rail that i am questioning.

have the plenum off,question is,there are two fuel linesoff the front of the moter.lines are pre -fab together.i guess i have to remove the one going to the fuel regulter and then they both pull off.factory manual is no help..

just noticed a fuel leak on my 90.it`s leaking at the fuel rail where the fuel line goes into the fuel rail.might be an o- ring? question...how does the line come apart? do i have to undo both fuel in and return lines all the way back to the regulater? i am sure somebody has had this apart...

sorry guys ,guess ididn`t make myself clear.after fixing the leak things are back to normal. thanks again.

thanks for the info guys, found vacuum line from the canister to inside cab,had a hole rubbed through.thanks again for the help.

maybe i should start a thread about what wax i use??

just unplug the blower motor, and put a test light on it or a volt meter,that will tell you if there is voltage .if not start checking fuses.if you have juice then pull the blower.

found several old threads on my latest a/c trouble.blowing out the floor and dash only.understand connector at module under dash is prone to leaking.real pain to get to.question now is where on engine is vacuum plummed to controler and does any body have diagram of vacuum lines...factory...

if the compressor failed,i would have the system flushed and evacuated by a pro .best bet in the long run .metal fillings can clog the orific tube and drier. spent it know and enjoy the cold air instead of of having it screw up the hottest day . also ...this work wonders for me i cleaned out the...

gotta tell just cleaned mine out.15 years of dirt and crap.that solved my weak air flow problem. never though it would be the simple cure,thought the mixiing doors were screwed up.a/c works great now...

Wade; have the same problems with my 90. how did you clean it out ,and is it any better?

well, it might not be by the book,but I have run into a few that the owner load with sealer. hook up the battery and crank the starter in short bursts.would be wise to pull the fuel pump fuse.
