Gas Smell in 360

Yup. You need to replace the pump (the circular thing).

Basically the plastic has degraded and you have a micro-crack in the plastic. The high pressure fuel is making its way out of the crack ontop of the pump (the wetness above). Crack is probably at the nipple where that rubber fuel hose fitting is connected. If you drive it long enough like this it will catch fire. Replace it.

 

Don't mess around with fuel smell. I can't say much now, but a friend if mine with a 360 just lost his car to fire the other day!
He is having possible issues with insurance so I can't elaborate until he resolves it. All I'm saying is don't mess around with a car with a fuel smell.

 

Pete, there are instructions here to remove it. there are some tight fits.. a ring of 10mm bolts holds the panel in and the run on the outside unscrews it. the pump is a bit expensive. if you're not too familiar I'd farm it off to a mechanic..

Chris please share when able anonymously if there is anything we can learn from..

 

I will definitely do that. The only thing I can say so far is to take any fuel smell very seriously. Another thing I can add is that just because a problem was "fixed" by a mechanic (even a good well known mechanic) it doesn't mean that a possible mistake can't be made, in turn, possibly causing a total loss of your car.
Sorry for being so vague at this time, I will definitely elaborate when all the facts come out and my friend says it's ok to elaborate. Insurance companies can be a pain.

Does that plate with all the bolts have to come off as it seems as if removing the large ring nut (#5) would allow the pump assembly to come out?

Alan, you can in theory remove the pump just by turning the "ring" (#5)that holds it onto the bezel. The passenger side fuel pump can in theory be removed by this alone. When I did mine I found that I had to remove the 10mm nuts in order to give enough room to maneuver the pump out of the car.
With the drivers side pump, you have the fuel level sensor that.. I've read mind you.. takes additional maneuvering and swearing to get out of the car. For the passenger side, I'd count on needing that plate and the bolts needing to come out. Its just a clearance issue with the fuel level sensor in the drivers tank.

 

Now THIS is interesting. I agree, I wouldn't post anymore until everything is finalized.

 

I had the same issue and the dealer replaced my fuel pump. Fuel pump made of plastic and indeed there was a hairline crack that's why I smell fuel once in a while.

I didnt want to mess around with fuel leaks so instead of learning or trying to do it myself I just had them remove and replace my fuel pump. Not cheap............

I have a post here somewhere.

 

You know.. I just looked at the spider parts diagram and there ISN'T a ring of 10mm bolts on the spiders! Interesting. I guess us Modena owners get the extra work..

 

that is not the roll over valve btw..

 

That should be the fuel line to the fuel injector rail on the engine. The line should go from the pump right to the injector rail.

 

Somebody needs to make a replacement part for the cap and attachments. They make one in bronze for the 550/456M, but it is over $400. Have never seen one for the 360.

 

If its similar to the Porsche and Volvo fuel pump heads then might just be as easy as buy remove and crimp. Only issue I can see is the pump output line is fused to the plastic. Might need a decent crimp or clamp for the pressure.

 

I recently replaced one of my fuel pumps on my Modena. Same thing the OP found .. smell of gas and fuel puddling on top of fuel pump cap. In concept, easy to to do the R&R. In practice, not easy to do. Access is difficult, removing cap took time. But, other than accessing the various screws, straight forward.

Well I read this post earlier today, then went for a cruise tonight and how lucky..strong gas smell. Removed access panels and sure enough gas on top of pump. Cleaned up and started car up and filled back up slowly. Will order new pump tomorrow. So relieved I have the access panels!!

 

I'd be thnking depressurization of the fuel system and the CEL code or lower fuel pressure leading to injector issues and the code..
