Fuel filler cap is leaky.

Usually compliance, they dont use fuel resistant sealer around the insert for the fuel filler.

It'll cost you about $5-$10 for a tube from Repco from memory, follow the instructions and away you go.

i gota say...that was quick :P... i took a look at the sealer seems to be fine.... im gona re-seal it and see whether nething changes :ermm:.... if ne1 has any other suggestions (besides changing fuel lines) it be good to hear them just incase this doesnt work out and for ne1 else that might have the same problem :D

thanks

if it is the fuel filler seal you'll also get a fuel smell when you make hard right turns (fuel filler is on left). There's a couple of different sealers that I went through before I found one that worked. I tried Sikaflex 221, then loctite something. but these were soft setting so whenever I'd do up the petrol cap it'd turn the insert slightly until it eventually the seal broke. Then i bought selleys knead it, which is hard setting and i haven't had that problem since.

It is also worth checking the fuel lines running in and out of your fuel filter under the bonnet to see if they have aged...although the fact it only happens when low on fuel seems to discount this theory. I used to get a slight fuel smell in my car...found the lines had cracked due to aging and after I replaced them problem was solved.

Yep, well worth a look. Had the same problem with my car. As soon as I changed the fuel lines, it was all good.

Skyline fuel fillers are on the right :wave:

um im not sure if it makes the sound when fuel tank is open... i dont think so :S...neways i bought some hard setting gasket type stuff :S....it says that its fuel resistant so im gona give that a go tomorrow (it only cost 6.50) and i'l let u guys know....but from inspection the seal looks alrite..but i do remember seeing lil lines coming down the quarter panel..so jeh lets hope its that and not the fuel lines...cuz i seriously dont wana go through the pain of taking off fuel lines from the fuel filter :@... that was the biggest bitch in the world

I am having a similar prob with my R33 GTST. Fuel smell now and then. I thought it was over sized injectors, but now I am not so sure, maybe my lines have perished. Wont be the filler cap because the smell is entering the cabin whilst driving straight, like its being blown in. Will check lines next weekend...piece of mind I have an extinguisher on board!

I'm getting the fuel smell now, after changing my fuel pump last weekend. My tuner suggested it is the black round rubber fuel tank seal (not on the fuel filler cap), its the one inside the boot under the plastic cap that seals the tank. It is a b*tch to fit and the big plastic cap screw-on that comes after it is worse, have to tap with hammer..

Car is R34 and I think I got the seal in right - had to wedge the edges in with a flat screwdriver, but still theres a smell from boot area??? aaaaarghh - do i need a new seal or re-fit the existing????

U mean u dont have the rubber seal insert? Man thats dangerous, u can have a lot of fuel leaking out / poor fuel economy and danger from cigarrette smoke / spark etc

Thats one old thread you revived buddy lol.

Check the hoses mate. I had the same problem with mine after I changed the fuel pump, you put in a higher output pump? Open up the flap where the fuel pump is located, get somebody else to turn the ignition on and see if fuel squirts from a crack in one of the hoses. Mine was a split hose and you are only able to tell once the car was switched on.

I don't have the piece of metal that restricts which pump nozzle u can put in to fill the car. My fuel tank and associated pressure etc is fine. I just have the normal factory fuel hole :P which is exactly the same as the one I had in my aus delivered pulsar before I bought the skyline. All I'm in danger of is accidentally putting diesel in... Which I'm not stupi enough to do

    • Hi all,   I have been a member here for years and am back to owning an R35.  It's my car and thought members of the community might enjoy sharing my journey.  I am definitely here to join the conversation.  If sharing this content isn't appropriate or it belongs somewhere else, I am happy to have it deleted or moved...
    • Data looks rock solid? I'm assuming you jabbed the throttle twice OR once? the TPS voltage moves up and down twice, however you've mentioned you did it once.
    • Having not watched the videos, I'm unsure, but this may be better suited to the importing thread?
    • Update on this situation: (Forgot to put in my previous post that I bought another brand new pressure gauge and fuel shows the same 50psi) I've deleted all the aftermarket immobilizers and turbo timer shyt and placed all factory wiring back to normal. The problem is still the same and nothing changed, but atleast it's a bit more tidier under the steering wheel. I've also siphoned out all the old fuel and then poured new batch of BP98 fuel (about 15L) into the tank. Nothing changed. Still the same idle. I also changed out the MAP vac line with a new one and, still the same.  So 2 days ago, I thought fk it. I'll just change out the fuel rail and injectors with another set that I know worked well in my brother's R34 a while back. That other fuel rail has the exact same Xspurt 640cc as what I have right now. So I changed it out to that other fuel rail and injectors (new O-rings) and injector harness. Put everything back together, started the engine, 464906286_1624569924763105_5179888796065901094_n.mp4   and yeah... still the same 50psi and idle problem. 🫠 I can also hear each of injector's solenoids running when I put a screw driver to it and have the other end to my ear. I might get a noid light just to confirm pulsasion but yeah, very strange that both fuel rails and injectors put out 50psi.  31-10-2024.csv I've attached it here. I started recording, then started the engine and let it idle with no throttle, then at the end I applied a little throttle and then stopped recording.    So, now idk. I'm going to see if swapping out the brand new R35 coils to my old splits fires will change anything. 🤷‍♂️
    • Hey mate, nice work on the car. Just a quick note, people generally don't like it when you use the forums to dump and run to advertise your YouTube content. If you're gonna stick around and join in the conversation then great, but if not this might not be the best place for you.
