Did anyone ever find a suitable fix / replacement for the fuel pumps that crack ( plastic top ?) and leak / give off fumes within the cabin of the 599/612 ? Replacing the originals with new OEM parts only delays the problem coming back. I thought I read somewhere here that a member had engineered a fix, or was it that Ferrari re-engineered the original part to eliminate the problem. Considering the potential damage to the vehicle, not to mention life threatening possibilities of what is basically a design flaw, I would've thought it would have been a priority. Were they ever subject to a vehicle recall because of this ?
