Fuel Smell, Possible Leak?

[shubby0901]

Hey guys,

So I just joined this forum today and took delivery of my new (not really new....or close to new) R33 GTST. Had it mechanically inspected and mechanic said it was all good but upon filling up fuel at the pumps, there has been a constant fuel smell from the pumps all the way home. At home, the smell seems to be getting worse. Had a look under the car and under the tank there are 2 rubber grommet things with a liquid around them but it doesnt smell like fuel.

Car is absolutely stock, got a sound system but I dunno if that counts as a modification.

Any thoughts?

Thanks

Sure the Fuel pump hasn't been replaced / upgraded? Is the fuel smell stronger in the boot?

Sounds like the seal around the fuel tank access lid has been disturbed or fuel hoses leaking.

Under the carpet on the right side on the little shelf behind the back seat. Remove the 4 bolts and square panel.

Under there is the lid thingo with the electricals and hoses for the fuel pump. Check it. (no naked flames)

So upon further investigation, it looks like the rubber grommets I was looking at were just ones in the bottom of the boot where the wheel sits, the liquid is just water from when it was washed. Dunno how it got there but that is a seperate issue.

From what I know, nothing has been changed. There is barely any smell in the boot itself, its all very focussed around the fuel filler cap thing. It seems like that's the part that's leaking as there is barely any smell anywhere else.

I will try and check that tomorrow and see what I see, atm its parked outside cuz the smell of fuel is all over the house.

Water in boot is likely from boot seal or taillights leaking.

Fuel filler tube / snorkel dealies can need resealing. In the daylight you will likely see fuel vapours escaping from the filler.

Do a search and you should find a thread about this exact issue.

Again, No Naked Flamage.

Lights leaking makes sense, I will fix them sometime, dont think rain is an issue for a while.

As for fumes, I drove the car and looked and saw no fumes. The guy at repco said the fuel filler cap could be faulty so I shall get a new one and try it out.

Yeah, could be the cap also. A fresh one can't hurt.

You can try a new cap, but there's a restrictor put in your filler neck that the cap screws into with the flap in it, this part eventually leaks but you can take it out and reseal it with a petrol friendly sealant.

To get it,

open fuel flap

remove fuel cap

get some pliers and a big flat blade and pry/wriggle it free from the neck

silicon behind the lip you pry from and reinstall

Youll notice this leak most when you have a full tank of fuel and you load the car turning hard left. I had fuel running down my rear quarter panel

I hope this helps

Changing fuel filler cap did nothing. Smell still there.

Is the lip you are referring to the rubber ring kind of thing that sits around the filler neck?

Similar to the one shown in this picture?

As for the neck needing resealing, i see no movement so I don't know how difficult it will be to remove it. Most people in that link seem to have movement in the filler nozzle.

The smell is definitely from the filler as it is strongest there.

Also during the day, the fumes arnt really visible but if you leave the car with the filler flap closed, and then open it later, you can see alot of fume escaping and then it just stops.

Massive picture, my apologies, i just googled and found a picture that was closest to my needs.
