Hey everyone i have the Ze swap done about a year ago. and i always smell gas. I can drive around normal all day and smell no gas. I have checked there no leaks or anything. But as soon as i floor it i can smell gas so strong but none is on the ground. I dont understand.

Exhaust leak?

I have a GS with just K&N & minor mods & I smell gas usually, too. I'm sure I don't have a gas leak because I get 33-35 mpg on the highway. I wonder if it's normal to smell it.

It couldn't be coming from the fuel tank could it? It sounds weird to me that there would be a fuel smell without a hole in the tank, a fuel line, fuel rail, fuel inector, or the exhaust (or engine for that matter, but a gas smell would be the least of your worries in that instance hehe). The only other thing I can think of would be if there is something really screwed up with the EGR system and it leaks when it is actuated (never heard of this happening before) in which case, that would qualify as a high rpm exhaust leak. I don't know much about the VRIS but that kicks in when you step on it doesn't it? Is that capable of leaking gasses? And I guess there is the charcole canister and the line(s) to it (don't think it would be associated with "stepping" on it though). These are just a few ideas in terms of where fuel can come from (because it is where there is fuel).

Maybe you could see if someone could smell where it is coming from when you rev it

ah ha.. i have found out whatcha are talking about.. i too smell gas..go crazy look around and no leaks.. i drove her around for awhile..build up some pressure inside the tank and come to a stop..sure enough i smell it.. try opening gas cap..whhaa no pressure, took inside cover off from left rear wheel, and yep there's a fine crack along the fill tube, and the plastic tube that connect to the fuel tank seem to be going too.. replace em both, and no more crazy fuel smell.

another mx3 mystery slove, well on my car that is

Same thing happened to me with my V6. Only where I come from we call it petrol and not gas!

I tried getting on the UK mazda site but I think somebody stole this site and changed to the UK but cant register.

Anyway back to my problem, I called out the recovery guy and low and behold my tank has rusted and split half way up. If I keep fuel less than half a tank then no spill, unless hard cornering.

The guy suggested getting it sorted ASAP but also suggested that off the record if I run her low shouldn't be a problem. This is no good for me as I only just got my car and do not want her bursting into flames.

Also there are no UK workshop manuals only the US or jap import manual which are rare to find in the UK. Anybody got step by step how to remove and refit a fuel tank on the V6 24Valve

I believe you go from inside the car and remove the rear seats 1st.

Cheers Matt from the UK

umm check your fuel injectors the seals around them might be blown or something, then when you punch it you might get a little leaky leaky that hapend in my winter beater. It makes it worse when you crank the fans up too.

Shawn, you should be getting way more mileage than that. A minimum of 400km with constant aggressive driving and at least over 500km per tank with strictly highway.

On my brothers mx-6 when he did the klze swap he ran the stock ecu for about a week and it smelt like major gas sometimes because it would send to much gas to the engine sometimes and others not enough so if you have your stock ecu check tht

mx-3_rider · Post by **mx-3_rider** » August 15th, 2006, 1:55 am

running a stock ecu on the klze it kinda bad cause the ze are way different than the stock motors... look for a kl36 j spec ecu or go to mx6.com and look for a guy his name is probenator something like that.... there 55 shipped...

Hi I might know the answer to this mistery!

Pretty shure that this smell comes from the charcoal filter canister needs to be replace.

It's located on the right side of the engine bay hanging on the firewall

I say so because it's happening to me, no fuel leaks anywhere, so after driving a while in hot wheather it shows up real strong smell.
