gas smell inside the car
 

Ive seen other this posted up before but couldnt find
it in a search.
I have a customer who gets a distinct fuel smell inside the
cabin from time to time..
I was thinking it had to do with the venting system for the
tank, or something with a vaccum line under the dash that may
of cracked or broke.
any ideas, lmk

Probably just the rusted out fuel line from the gas tank...

I would probably start digging into that area.

Check the simple stuff first. I had a strong gas smell on startup that dissipated once I got rolling. Problem: A loose hose clamp at the fuel filter.

I had a leak where the fuel lines come into the car from the back. Lift up the rear seat bun and check there?

check all the wire grommets maybe some are loose

a good shop uses a smoke test..
they put smoke thru all the vent lines to the
tank and charcoal canister etc to find the leak.
Its not leaking fuel, Im sure of that, but it has to
do with the charcoal canister and vent system the
epa mandates all these cars to have since the 70s.

I've dissambled every single detail in my interior to bare metal.

The areas that separate the inside of the car to outside of the car are prone to being smelly are:
-the rear left vent on the inside of your bumper, maybe there's fumes coming in from there.
-On the firewall there really isn't anything that a leak could cause a smell to come in.
-there are those manufacturing holes on the floor that have gromets, maybe some are missing
-the fuel tank panel rear of the rear seats.
-Blown heater you'd have that shocking sweet coolant smell no matter if the car is on or off.
-leaking gearbox fluid is pretty potent too.

There are no vacuum lines inside the car that I know of.
the only lines in the car that I know of are brake, rigid heater pipes and heater of course and aircon rigid pipes and evaporator

When I floor it I get a little smell coming in too, but my main engine oil seals are leaking between the engine and gearbox, so that's my suspect.

Check my photobucket profile for images.

For aircraft you can buy this CO Carbon Monoxide sticker and it's yellow, CO makes the sticker colour change to red and indicate CO leaking into the cockpit, try and source one of them, I don't know how much they cost.

It's unlikely, but you might wanna check for this on the passenger floor

I had a mystery gas smell for a few months a number of years back. Turned out to be the gas line which runs between the gas tank and body had rusted just enough to weep. Mechanic needed to drop the exhaust then gas tank to fix it.
