Hi Folks,

I recently got a surge tank installed along with a few other mods - Ever since then, I have had petrol smell wafting thru the cabin. I've looked for leaks , but can't find any. The economy has gone down, but that may be from the mods - But it also may be from a fuel leak somewhere??

Oh, I also got a big mutha Bosche in-tank fuel pump installed at the same time.

Anyone else have a surge tank and have petrol smell ???

I've looked at how the fuel lines were run, but can't find anything odd. There is a gap where the surgey fuels lines come out of the top of the metal plate above the tank - but the fuel tank is still sealed with standard fitting.

I've also been told that some fuel lines 'permeates' fuel - which I find and interesting concept..

I might have to take the surgey out to see if the smell goes away..

/edit: I have also checked the filler cap/neck - tis OK

Anyone got any other ideas - ?? What should I be looking for ??

Cheers,

  • 11 months later...

Well I have a stock '93 R33 and when I go for a drive, be it 5 mins or an hour, once I stop and then let it sit for between 5 mins and 2 to 3 hours later I get the smell of petrol through the cabin, not overpowering, just enough to be really annoying. I dont get it when I am driving though, only just after I stop, not instantly either?

Funny thing is that if left overnight, sometimes it smells and sometimes not?

So please explain to this ignorant noob where to start I notice in other threads on this subject to check the filler for some type of seal, what exactly am I looking at/for? Also I have looked at the underside and engine bay for any petrol leaks, but to this untrained eye I cant see any obvious ones, no petrol dripping out of anywhere and no wet looking areas, but then again I really dont know what/where I sould be looking at/for.

It does not seem to be getting any worse or any better in the 3 months of owning it, so at least that's one thing :cheers:

Oh yeah, apparently some compliancers use silicon or some sealer that is eventually eaten away by petrol to install the fuel filler neck. Get this looked at.

T.

Its called SIKAFLEX and th RAWS CAN NOT use this any more. This is what the cheap barstards used to use but you got to use like a cement mix thing now. I dont work out the back that much so i dont know what its called. But yeah that could be it. As it gets eaten away very quickly.

Hijack away fellas - I fixed my problem by taking the surge tank out - the rubber lines that went to the fuel tank seeped fumes - so that was my problem.

I'd be looking at the filler cap

Old lines

It's horrible smell I know - thankfully mine is fixed - When I get another surge tank, I'll be using either metal/steel/nickel lines or that special silicon (i think) non-seep / non-smell line

    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way. Simples
    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
