Dear members
I am getting a smell of gas/ petrol in the cabin.
I have replaced the rubber pipes and hose clips in the boot/trunk some years ago when the smell wasn't too bad , but it's getting worse now and I am wondering if the vapour vent components are responsible.
If anybody has a suggestion that might help me with this 1984 model, I would me very grateful.
​​​​​Kindest regards
Danny.

 

Hi, do you get a pressure "wooosshhh" release when you open the gas cap ?

 

Thank you so much Jose for your speedy response as always to my queries.
I have just gone to the garage where the car has been standing overnight since 6pm last night.
I opened both caps and listened closely for a whoosh but nothing was heard from either cap.
The springs and rubber seals seem ok.
Thank you once again Jose

Kind regards Danny.

 

There are numerous potential leak areas. Any of them can result in fuel odor in the cabin.

Take a good look at the hoses in the engine bay. ALL of them. You may have a leak. Often overlooked is the small section of return hose at the front of the cylinder head.

Underbody fuel pipes can rust away. There are hidden hoses at the left and right fuel return valves. You'll have to remove the rear wheels to inspect. They're hidden behind tin covers.

Each "C" pillar has a fuel condensation cannister. These can rust away. You can inspect by remove the pillar trim inside the car. Plus the hoses under the rear package shelf that connect the cannisters to the vent system.

And another source of the fuel odour (in my experience) can be the small hose that goes from the rear pillar pipes to the fuel filler unit. If you open the filler cap you will see the hose at the front end of the metal filler assembly. I had this come loose on a 1989 Series III car…a pair of needle-nosed pliers works well here!

 

Thank you so much for your suggestions.
Very much appreciated
Regards
Danny.
