Strong Fuel Smell In R33

[Kiwibob]

Hey there,

i normally put 98 from the 7-eleven close to me but thought i would try Shell V-power to see if it made any difference.

It seems to pull a bit harder than before so that is good but now there is a strong fuel smell inside the car which wasnt there before i put the v-power in. Now i checked to make sure i didnt leave the cap off which i didnt. Does anyone know why?

I heard that when the cat starts to die there is a smell like that from it but it has happened very suddenley.

Any help would be great.

thank you guys and girls.

Oh it is a 95 series 1 gts25t

it could be caused by 1 of a few things, but i doubt any are due to changing fuel, it was just purely coincidence. 1 may be that the seal around the fuel pump is a bit dodgy and then once you actually filled the car up has leaked a bit. another is that the filler neck isn't sealing properly behind the cap. another is that you have a leak somewhere in the engine bay, such as an exhaust gasket. or possibly the cat is dead, but i don't think you usually smell that in the car.

i'd say that the smell is more due to having a full tank of fuel and to check things like the seal around the fuel pump.

Cool thank you for that. i will have a check tonight. I have filled it up plenty of times before and no smell but then i do know that seals do let go randomly.

If the cat was dead then i would notice a bit of a power drop, not an increase like i have had now. I was hoping it was the cat so i can convince the mrs that i need a WHOLE new exhaust

[mad082]

depends on how/why the cat failed. the cat may have failed due to being a bit blocked, and therefore once it has let go then it will be letting more air through and you would notice more power.

well the car was imported about 4 years ago and it is completley stock so i would say that i will replace the cat anyway because it will probably have one of those horrible complaince cats on it.

Thank you for your advice. Much aprecaited

[Mr Eps]

is it "exhaust" fume smell???

or PETROL

if it's PETROL. as in unburned fuel... check your injector o rings.

i have this problem.

it is not cool.

[Kiwibob]

hmm good point. When i drive home tonite i will try to see.

damn i dont like your reply, the other solution sounded much easier and cheaper.

so i guess if it is that then replacing o rings would be the only cre. that sounds expensive.

if you have removed your carbon canister its also a location for fuel vapours to escape

[Galois]

if your carbon canister or its purge control valve are broken the vapours can escape too...

Now this will show how inept i am with cars. Where is the carbon canister?

i think i have eliminated the leaking o-rings as it is not as bad now as it was earlier. so this answer sounds like what it could be.

haha i wouldn't know if my dad didnt touch some random valve and break it forcing me to find out what it was lol (hence the signature). if ur looking from the front of your car down at the airbox snorkel, its the black cylinder with 2 pipes on top nearby, probably 6cm in diameter and 15-20cm deep

the control valve is the one with the blue plug at the back of the engine bay, towards the firewall
