Does your car still have the Charcoal Canister in it?

If it doesnt you way find that on the end of the fuel tank breather line(which runs into the bottom of the charcoal canister) may be open free to air or have some kind of breather on the end of it. Have seen this on a couple of R32's GTR's and GTST's...

Just a thought anyway...

Good luck!

You will find the charcoal canister behind the front passenger side head light.

See here:

And the fuel tank breather line (I believe its called) runs into this canister aswell as other verious vacum lines.

Check if you still have this...

when i went searching for the smell it located in the rear of the car not the front, but could never pin point the location, my guess is my problem was something to do with the fuel tank or lines, so go searching next time you smell it

Hey There

I purchaced a S13 3 years ago and had the same problem, It smelt like fuel on the inside of the car, I got the Charcoal Canister changed but I still had the smell, I took it to another mechanic who deals with Skylines and he said that the problem is when they change the fuel tank nozzle over to one for Aus, they sometimes do not add enough sealant and the fuel smell can come out of there.

I added extra sealant myself and the smell was gone completely.

Hope this helps

Yeah have read that...

Noticed this post:

If the fuel is actually leaking out from the filler area, it's probably not the seal on the bung for the fuel pump access.

It's more than likely a poor compliance when fitting the new filler neck. As part of the comply, they fit an adapter in the filler neck to suit the small diameter bowser fittings of unleaded fuel. It's sealed inside the factory neck with Sikaflex or similar but if it's not done properly, they smell and leak.

A quick check is does it go "whoosh" when you open the cap? If not it's leaking somewhere and thousands of Skylines have this filler neck problem.

It can be fixed by getting it sealed properly and is usually an overnight job to allow the Sikaflex to cure properly.

I have the exact same problem on a 33... Mine appeared when i changed the fuel pump over (bigger pump)... Some times almost makes me pass out when driving rediculously hard! It is strange how i can only smell it when the car is being pushed hard! Make me think the seal for the fuel tank was not put on properly when my boshc pump was put in... Will investigate when i get time -- not really in a hurry to get it fixed. Just so long as it doesnt catch fire or blow up when some one is smoking around it!

      GOT SUM's RB34

      By klutched · Posted

      Got some decent progress after work yesterday and also today. Got the ECU all wired and passenger side interior all back together. Kept the wiring up nice and high to avoid people standing on it. Got the surge tank relays rewired and tidied up the pump wiring and cut a hole to bring the cables through.  I found a spare USB cable I had lying around so I decided to cut it up and see if I could use it for my CAN 1 bus. Turned out one of the pins I needed was to the shield of the cable so i cut it up and desoldered it and resoldered to the correct pins.  Had the issue with the powersteering hose hitting the A/C compressor and fan shroud. I pulled the bracket off and modified it to remove the front mounting point which now clears it all. Will keep an eye on it to see if theres any signs of fouling once it's up and running.

      So today I went well outside my comfort zone (again) to replace my valve cover gasket.  I have had a big leak over the exhaust leading to a lot of smoke and smell every time I drove it. The leak was in the rear driver's corner.  The job wasn't hard as such, just a bit finicky and time consuming.  The old gasket was rock hard and broken right where the leak was.  The leaky corner had so much sitting oil in it.  The good news to my amateur eyes was no buildup or sludge under the cover. It all looked fairly nice in there.   I haven't started it yet. I ran out of light and body when putting the coils and injector loom back in. Probs only 30min left for the morning.  I was so nervous putting the cover back on, I must have lifted it 5 times to make sure the gasket was still seated properly. God it's going to be nice to be leak free and not make other traffic light queuers think my car is about to explode.

      Gave the Mazda it's first wash, it will need some clay, a light compound, and polish polish to remove a few swirl marks, but that will be a job for when I have a full day to get my DA polisher action on

      Just did this job on my 32 with the boost doc kit. was quite simple to fit, hardest part was getting the rubber bungs back on the firewall. does anyone know how the heater will work now without the flap in the bend? Will I just have a heater on 24/7 now?
