my r33 gtst has recently been letting off a really bad fuel smell within the car. after ive been in the car for 15 mins or so i start to get a pretty strong smell of fuel.

i have checked under the car and theres no leaks to be seen so i have nfi what could be causing it? is this a serious problem?

on a side note, does anyone know where u can buy replacement break lights for the r33 S2 spoiler? the break light was loose on my spoiler and its fallen off :\

I have a similar fuel smell only becomes bad with the sunroof open and windows down? I get good fuel economy and Ive had two mechanics check it out but didn't find anything. If you find the problem post it up, prolly a common issue.

I started to get a bad fuel smell, but I had really poor fuel economy - was running rich, hopefully it goes away with the next tune.

Is your filter :( plastic or metal construction.

Sometimes this can be a faulty unit.

I have had 2 fuel filter go on me to date...both nissans.

But yeah...you just picked up your car so, get it checked out....You can normally feel with your hand around the hoses to see if there is a leak. You can also smell were it is coming from normally.

Good luck and hope I have been of some help.

Yeah, i get fuel smell around my filler and in my engine bay. Not noticable in the cabin though....might have to inspect this fuel filter. Where can i locate this in the RB20DET engine bay?

*had my car for ~4 months (purchased complied and serviced)

Cheers,

Steve.

as mentioned, it's often fuel cap, also those temporary ones you get from servo's. You end up having the fuel in the tank splash against the cap when going around corners + fumes = bad smell!

Also if you have changed your fuel pump recently and broke the rubber seal around the pump housing .

try going to supercheap and buying about 3metres of fuel hose and about 6 new small hose clamps

then when the car is cold, look under the hood and find the fuel lines in the bonnet. there should be 3 rubber hoses:

1 - from teh bottom on the engine on drivers side to the fuel filter

2 - from the fuel filter to the fuel rail

3 - coming back from the fuel pressure regulator to the bottom of the engine bay again

i replaced all hoses and clamps, and my fuel smell went away :laugh:

if you are going to do this, i suggest also replacing the fuel filter while you are at it and i even relocated the fuel filter to be within easier reach.

when doing this, remember to remove the fuel pump fuse and crank the car for a few seconds first to get all the fuel out of the lines...

it can't hurt to do it even if there's no problem, as hoses get brittle after 15 or so years of being exposed to 100deg temps!

cheers,

Warren

    • Cheers. Skyline is back on the menu, can’t get rid of it. It’s like a child you don’t want, or herpes 
    • I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.  
    • Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days
    • It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
