    My mechanic gave me a melted hose which i took to the dealer and replaced. My mechanic took ill and I cannot figure out where this tube goes. In looking for the end of this hose I found that the hose from the breather, which runs to the back of the engine is also not hooked to anything. I am getting a check engine light.

If u mean a plastic tube the runs from the bellow on the throttle body to the rear cylinder head , just below the coil pack,,, metal tubes are the gas lines or the injector rails , and bottom of the EGR valve has to metel tube the runs the exhsust manifold,, your under hood decal should have your Vaccum diagram on it.. if thats the breather tube your engine should being running very rich= burning a lot of Gas!!!

95 sl500 fuel tank holds a lot of pressure,idles rough when stopped at idle speed Where is the fuel tank breather hose?


There is no breather hose for the fuel tank, the system is designed as a sealed system to prevent gas fumes from polluting the air it is called the "Evaporative emissions control system", and yes some systems can have alot of pressure in the tank esp on hot days or after a long drive.

On my 2000 ford windstar i cant get fuel to go in the tank it backs up in the fill tube and runs back out,what could cause that?


Rick ,is there something blocking the hose to tank? or is the hose kinked , the tank must have a breather tube also working to allow fumes and pressure to come out of tank or fuel will back up.

Evap system


The FSM is clear on this. each hose and fitting must be air tight.
or the the car vents gas fumes full time, and the EVAP ECU tests
(monitor) make sure this all works.
you can just look at the left and right side above rear tires. and see
if your hands are small enough to fit here. Id bet not.
some mech, report, the tank can be tilted down at front (drained fuel)
and gain access.
keep in mind, you get fuel siphoning at any time. do not open the system, with fuel in the tank, and then drive to autozone,
i loosen the gas cap so that pressure can not build in tank.
expanding fuel can push fuel out , during a filter change. very
dangerous in a garage, and you gone.
it's just a vent hose, you can see, it and what needs to be done is really obvious. given you arms sides and lenght.
my fsm states, " TANK pull"

Removal & Installation

  1. Relieve the fuel system pressure and disconnect the negative battery cable.
  2. Remove the fuel filler cap from the fuel tank.
  3. Have a Class B fire extinguisher near the work area. Use a hand operated pump device to drain as much fuel through the fuel filler neck as possible.
  4. Use a siphon to remove the remainder of the fuel in the tank by connecting the siphon to the fuel pump outlet fitting.

  13. Remove the fuel vapor clamp and hose, and fuel return hose clamps and hose from the respective fuel lines.
  14. Using a suitable transaxle jack, support the fuel tank.
  15. Remove the fuel tank retaining bolts and lower the tank.

Line that goes from pcv to carb


It would be called a PCV hose, or an Engine Ventilation hose.
It directs engine crankcase fumes into the carby, air intake system.

I get a petrol fume smell when i am driving


You have a leak, inspect very thoroughly, find someone with a good nose who can sniff around when you've stopped the engine.
Look around all the places associated with fuel, filler pipe, breather hoses, fuel lines and unions, fuel filter, any flexible fuel hoses, fuel tank and sender etc. Look for tell tale 'wet' patches. If it is very strong you need to find it as it is dangerous.

I hope I have been of help but please do not hesitate to ask if you have any further questions.
I appreciate your vote if you appreciate my reply.

I need to change my fuel tank on 94 pontiac grand am. want to make sure i am going to do it right


Try to have the tank as empty as possible.This will help in the removal process.Relief the fuel pressure by removing the fuel pump fuse or relay and start the car and let it run til it kills. Remove the straps that hold the tank in place and loosen the hose clamps to the filler and breather hoses.Lower the tank enough to unplug the fuel pump connectors and lines,remove the tank.Be very careful around gas or fumes.They are very flammable.Safety always.The amount of money you save is not worth you getting hurt or killed.

Fuel Odor on a 1998 Jeep Grand Cherokee


The evap system ( fuel vapor recovery system ) , if there is a leaky hose, can let fumes out that can be detected in the cab. If you "top off" the fuel at the pump you can spill fuel into the charcoal canister meant for fuel vapors only. the vapor recovery system is behind the left rear tire.

Usually if there is a hose leak a check engine light will come on.

If you TOP OFF, don't. If you don't, good. Hope this helps.
