hi there my zed had a really strong gasoline smell .. where i couldn't fix this problem after going to 2 mechanics .... if the zed mechanics i m going today still couldn't figure out .....i 'm going to give up my zed.... :thumbsdown: i am so frustrated ... do u guys have the same problem as my zed ??
Fuel filler, or fuel lines in engine bay One of the two. You'll find the pressure differential of having a window down will make it worse. If it's the fuel cap, buy some fuel neck filler putty from your local auto store and putty up the area where the new filler neck was brutally attached by your compliance workshop. This helped on mine. Also, pull the plenum and replace all fuel lines. I had fuel leaking out of one of my fuel hoses. I replaced my injectors and fuel lines and have not had a wiff of fuel vapors since, except very small trace amounts from the fuel filler - the putty is not the be all end all.
I had to replace the fuel filler neck twice. More recently the gasket on the end of the screw on cap came ajar just a little and i thought I was getting a tight seal but wasn't. Instant strong petrol smell. When I realigned the gasket it seals perfectly and no more smell. Good luck matey Geoff
Fuel Cap Do you know if the filler cap is available straight from Nissan??? mine has NO rubber at all ... I think that is why it leaks like a seive and smells alot BTW mine is an import 2 seater
not fuel cap i think its not the fuel cap problem its the 'fuel gas' actually leaking out .... when u reomve your fuel cap u can hear some 'shhh' gas sound but now the gas are gone and no sound when i remove the fuel cap I have overlooked the base and pipes of the car and in the engine with a mechanic ... no signs of any leakage .. i was amazed can anyone tell me what's going wrong? what i know this petrol smell is very common in 300zx
The usual suspects ... You have to go thru these and rule them out one by one: * Fuet Tank and Cap/Filler area?(as already suggested) * Fuel lines from tank including Carbon Canister? * Fuel filter (I've seen one that was leaking vapour from the seal)? * Injectors leaking? And last because it's a mother of a job... * Under Plenum hoses? Also, when are you checking it- Hot or cold? Try checking when it's stone cold... See this link for additional ideas.
