612 fuel smell

Quiet sure it are the gaskets of your fuelpumps.

Peter- Cracked fuel pump covers are common, and so are leaking roll-over valves.

 

Here (see photo) is probably your problem. I had all the same symptoms, fuel smell but no leaks under the car (the panels mask that). The plastic cap over one, and maybe even both, of your fuel pumps has likely cracked. The apparent good news is the replacement is much better than the original. Even if this turns out not to be your problem, I would not drive the car until you find out the source of the fuel leak.

The photo shows the gas streaming out of my fuel pump cap on my 2008 612 OTO in October, 2015 at 16,309 miles. Today at 47,847 no problems.

BTW, once this happened I now keep a halotron fire extinguisher in both my Ferraris.

Well if your leak is from the same spot as my photo, you will have to replace #2, the fuel pump and #4 the gasket (#3 should be fine). My cost was $655 for the right hand pump and $30 for the gasket. The left hand pump (depicted in your diagram) is actually a little less because it doesn't include the fuel gauge lever. Of course this is 2015 prices, your results may vary.

 

Curious to find out if part number 2 has cracked, or whether the o-ring on the fuel pipe connector has just let go? I suspect its the former, but if it's the latter, you might be able to fix the leak with a 50c o-ring.

 

Robin, 50c o-ring? Read my post again, it was $30, probably £50 to you!

 

Yup this has been a Ferrari problem uncorrected by Ferrari since the 1st 550 at least. The gift that keep on giving....

 

I was getting at the little o-ring that there will be on the fuel pipe connector, as opposed tot he big o-ring to seal the fuel pump to the tank.

I suspect this is wishful thinking though!
