I have to replace the fuel filler neck...Finally discovered that after 2 years of smelling on/off gas fumes, that my fuel filler is defective.

I bought the part from Honda, but does anyone know if this is a hard job to do on one's own? The only bolts I can see are the one's holding the filler neck in it's place where the gas-pump is inserted. Other than that, does the fuel filler neck connect to the fuel tank easily?

I looked through some threads, and one mentioned that the gas tank needs to be dropped. I really hope this is not the case, so all help is definitely needed/ appreciated!

there is a tsb on that issue, mine was replaced by honda as a warranty item.

it is accessed by removing the trim panel in your trunk.

There are four bolts to remove the fuel filler neck (three on side of the car and one bracket). All can be accessed from the trunk if you remove some trim panels.

The fuel filler does not directly connect to the fuel tank. Instead, it attaches to some rubber hoses, which attach to the tank. So you just need to undo the hose clamps and pull the hoses off the old one, then put them on the new one.

You will have to slide a rubber cover up in order to get to the hose clamps.

Anyone have a copy of the TSB?

TSB only applies to 2002 and early 2003 MY cars. TSB04-002, IIRC.

TSB 04-002 is correct. If anyone wants a pdf copy of it, just shoot me a PM with your email address. The TSB applies to all 2002 S2000's and 2003's with VINs 0001 through 7688. Mine was out of warranty at the time I had it done, but the dealership said it was a 'safety issue' and did not charge me.

I may have a different issue then. I get a strong fuel smell only on very hot days (100+ degrees) and I drive the car really hard for long time. So it doesn't happen very often.

mikegarrison

You probably either have a crack in the metal tubes or one the hose clamps has worked loose. The "hot day" symptom probably just means that you need a really high vapor pressure before enough gas vapor leaks out to be noticeable.

I assume you can smell it more in the trunk than in the main cabin? Or have you tried that?

RevJunky

Nope, can't smell it from the inside of the car or the trunk. It comes from around the left-rear wheel well. I agree with you that the increase in vapor pressure probably causes the fumes to leak out from somewhere. I'm thinking it could be the vapor collection canister too.

I've had the problem for past 5 years and doesn't occur often enough to be a big issue for me.

Thanks for the help! Sounds like it should be an easy job. Without the smell of fuel now it feels like I have a brand-new car!
