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.

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????

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.

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

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

      M35 Aftermarket Fuel Pump

      By MBS206 · Posted

      Pressure when IDLING, is meant to be 51PSi... So that amperage value needs to go up a fair chunk... I'd personally be factoring for more like 12amp at least on those runs, and at that point you need to hope the already there wiring doesn't drop you a volt or two, as that's a lot of fuel pressure flow drop off from 13.5 to 12V! Taking idle pressure of 51psi, means the pump will be drawing a MINIMUM of 9amps all the time based on your reading of the graph (3bar base, then allowing an extra 0.5bar for boost = roughly 51psi)

      Wanted to buy R200 longnose LSD 3.9 ratio

      By Ben_D · Posted

      Hi all,  I am in the market for an R200 longnose diff out of a Z31 300ZX, or S12 RSX, DR30 skyline, or similar, in a 3.9 ratio.  Preferably a late model one with the M12 crownwheel bolts.  The only easy to find advert for one of these was my ad back in 2007 when I sold it on this forum.  I sold the diff as I had sold the car it goes to, but as it turns out, after 18 years I got the car back late last year, so now I'm looking for the diff !  If anyone knows where to find a longnose R200 LSD with the M12 crownwheel bolts, drop me a line at [email protected] - Bonus paid if soomeone comes up with the original diff (stranger things have happened !).  Cheers   Ben D

      Back for more after 18 years - and where are the longnose R200 LSDs?

      By Ben_D · Posted

      Hi everyone, I used to post here a bit from 2004-2013, when I owned various Nissans, in particular my S12 RSX gazelle, which was sold in 2007.  As luck would have it, after an 18 year hiatus, the car found its way back to me last year, and over the past 11 months I have had the pleasure of restoring it with my kids.  One thing that I am after in particular is a 3.9 ratio R200 LSD for it.  I actually sold the one out of the car here back in 2007 , and it would be incredible if I could track down who I sold it to, so I can see how they have progressed over the years (and to be honest, to see whether I can get the diff back !).  Anyways, hi all and let me know "where are the R200 Longnose diffs all at these days ?  Cheers Ben D

      G35 Control arm and Compression Rods into a V35 Skyline.

      By sonicii · Posted

      Arms will be the same as the G35 or 350Z, but as above, there was a change in the lower control arm where it connects to the ball joint.  That said, you can remove the ball joint cone from your old ball joints and fit them to the new ball joints.  To be honest, I didn't think the ball joints themselves were different. The main ball joint is a bit awkward to replace, you really need to remove the steering knuckle to press out the old one.  Some people have used tools to remove it in place, but it just seemed too hard to get to. If you are going to press out/in that ball joint, then you may as well just replace the bushings in the LCA and the compression rod.  You can buy the compression rod bushing from Nissan, but the LCA bushes, you will need to go aftermarket. Much cheaper than buying the whole arm.

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
