Commode ute fuel smell

[Ext User(Patrick Young)]

The guy renting 1/2 of our house has just taken his
Commode ute apart outside our house to check the fuel
tank which is under a panel in the bed just behind the
driver.

He didn't find a problem, I noticed a bit of rust on the
top of the tank.

His g/f reckons the smell of petrol is real bad inside
the vehicle.

Ideas?

ATEC could be spot on with this.
My brothers VR Statesman did the same thing.
The canister in near the radiator and the smell went into the fresh air
vent.
I put a length of rubber hose from the vent tube underneath the canister
and ran it out to the side of the mudguard.

No more smell!

A bit of rubber hose will fix it.

Many thanks!!!!. I'll pass this on. He is looking
a bit confused about it ATM.

It didn't make much sense to me that the fuel tank in back
would make fumes in cabin.

Done fixed, and on their way.
He had replaced the radiator a week or so back.

In this case he didn't reattach one of the hoses on said unit
when replaceing the radiator.

I really don't, and don't want to understand spark ignition engines.
Doing quite OK with turbo diesel... thanks.

i specialise mainly in trannies but i thought the canister sometimes
led fumes back into the manifold.

if so, then perhaps the fumes are resulting from a faulty valve or
something external of the canister itself.

is that possible?

When they are full, and that isn't hard to do if you overfill the fuel tank
on a regular basis they vent a lot of fumes to the atmosphere which often
drift over the vents and into the car.

That is the problem, and ask him if he fills his tank to the brim. If he
does, tell him not to to leave some room for expansion so the raw fuel
doesn't end up in the cannister.

Nope, the mixture is too rich.

He's a nigger and has petrol in a coke bottle sitting in the cup holder.

Be alert, but not alarmed!

i'm pretty sure the current emissions regs. prevent evaporative
emissions being vented to atmosphere. they'd have to go into the
manifold.

i've never checked on a car but i know how low the req'ts are and
there's no way you could allow fumes out past any way but the cat.

Normally yes, but there is a valve that can open to atmosphere under certain
circumstances, like when the cannister if full of fuel because some clown
has overfilled the tank.

Well you are wrong then. This is a pretty common complaint with a pretty
common fix, don't overfill your car.

ok you mean as a service operation, fair enough. i meant as part of
the emissions test cycle, which is just normal driving.

This is why it is illegal to fill a petrol tank past the first click off
of the bowser with the nozzle fully inserted - in NSW at least.

The consistent overfilling can cause damage. The evaporative emission
control equipment is thus _damaged_ due to illegal operator actions and
hence the operator is liable for a fine in the order of $50K.

Never heard of anyone being actually fined, and servos are never going to
make any effort to stop people overfilling their tanks - they sell more
petrol if it's dripping out onto the ground through the water drain on the
bottom of the canister...

Most don't have a separate valve as such.

The activated charcoal will absorb hydrocarbon vapours but not water. The
hydrocarbons and potentially water vapour enter the top of the canister.
Any water will condense on the outside of the charcoal granules and run
down to a drain hole in the bottom of the canister. If you saturate the
charcoal with hydrocarbons, eventually you'll get hydrocarbons running out
the water drain at the bottom.

Of course, when the canister is vented back to the engine, it is drawing
whatever is there... The hydrocarbons drawn out of the charcoal are
mixed with air that is drawn up from the bottom of the canister.
Interestingly, many canisters have a replacable filter in the bottom but
I've never heard of anyone replacing the filter. The engine will be
breating intake air through that filter and nobody replaces it!

You're both right!

It's not _legal_ for fumes to escape from the evaporative system as
described. It's also not legal to overfill the fuel tank to cause the
fault.

Erm, quite often I fill my Hilux *right up*, but I do then use it all
pretty much straight away (the place where I normally fill up is 110km
from home).

Should I stop doing that, or does it not really matter than much if
it's only that full for a few minutes at a time?
