car is throwing p0455 and p0442 and a huge fuel smell, so I check the fuel system and see what's the problem. simple question: for a 360 modena, is it possible to have a crack on fuel pump's top plastic parts that's not visible to the naked eye? I observed a lot of liquid gas in the grid shown in the attached picture but I can't find any cracks on the plastics. do I need a new pump in this case? Image Unavailable, Please Login
Mine did same thing. Crack not visible to eye, drip drip drip of fuel that pools on the top of the pump creating a fire hazard. Replace it. Worst case scenario possible is you let it go too long and the plastic nipple at the outflow to the engine cracks visible to the eye. All the high pressure fuel sprays into the compartment, catching fire and ***POOF***.
I just replaced the 2 Fuel pumps on my Maserati for the exact same reason. Looks identical to this photo. Seems like the plastic on these things last about 10-15 years and then cracks. Yes, you need a new pump. It cannot be fixed. Driving with a leak is a huge fire risk.
Mine had no codes! It's a euro 1999. I'm proactive with my cars and noticed that the garage was a bit too "fuel smell" after a drive. So I did the sniff test (sniff the holes in the engine compartment trim panels) and noticed a gasoline smell when there should be none. So I opened it and noticed fuel in the valley on the pump. Replaced. I predict the reason you got the codes, was the crack let the pressure out of the system and the switch on the tank detected it. Similar to leaving the gas cap too loose giving you an error code relating to evaporative emissions. I love my 1999, sooo much simpler car without the emissions crap.
I don't remember the codes, but the Indy Shop pressurized the fuel system with nitrogen that revealed vapor leaks from three of the four hoses/plastic fittings from the top of the two tanks (roll over shut off lines). Each hose cost $250 USD. The more I get into my 360, the more I see less than stellar parts/product/design quality. This is my first and last Ferrari I will own. These cars are fragile at best!!!
Honestly, you can't complain about a fuel pump going bad over 14 years. Your average Chevy or Camry is crushed in 7. I think this shows that garage queens don't mean that the cars are as good as they were when you put them in storage. Father time attacks plastic, rubber, leather, aluminum, and anything that can be oxidized or chemically damaged. My boss has a 60's vintage era Mercedes convertible. He drives it once a year. Last week he went out and found a river of gas running underneath it. Fuel line just got eaten up -- probably from Ethanol in the fuel these days.
Interestingly my 986 had a similar pump with no issues. I suspect the warmer operating conditions accelerate the breakdown in the 360 vs Volvos and Porsches. Different designs and component stresses on the plastic. 997 has pump under the front hood in. Much cooler environment.
i searched and saw your post about sniff test before I posted mine it seems that the liquid fuel you were having was on a different location (side) where I was having, is on the top , the "X" shape grid area
Looking at Ricambi's parts catalog, looks like the covers are available separately at a whole lot cheaper price than a new pump. Ferrari 360 Modena Parts : Table 10 - FUEL PUMPS AND PIPES They make an aftermarket cover for the 550, but not sure about the 360.
