Car Died on me for the first time
It was running just fine today and stopped for some last minute Christmas shopping, but when I went to leave the store today, I got a few hundred feet, then it suddenly started running really, really rough.
The car would idle, but as soon as you gave it gas it would start missing really badly. I was able to nurse it into a parking lot, but it barely starts now. Any ideas where to start looking? |
VarioCam valve 99610530371

in-tank fuel pump hose
|
Actually, it looks like the fuel pump went out. Got 3 lbs of pressure.
The bad news is that there are no pumps available in the US, so it has to come from Germany. |
These original pumps are a known weakness and the pump assembly has been subject to revisions and updates over the years.
Some folks repair the bursted hose with a part out of a Volvo catalog. I don't have the part number myself... maybe you can search for this online. I imagine that the parts store can supply generic fuel resistant hose for the repair. Porsche does not offer separate serviceable replacement parts for the pump's appendages as you probably discovered. |

it's likely the hose on the pump not the pump itself.

Is it time or miles that causes the failure?
|
127K miles on my clock.
I had a reputable indy look at the car and confirmed it was the pump that failed, not the hose. Not a big deal, I guess. |
I ordered a new OEM GT3 pump assembly from Germany a few weeks ago. I only need the lower part of the basket so if anyone wants a new pump with the lines just let me know..
|
My pump failed this year too. The whole upper green assembly was cracked. The pump flopped around during long hard left hand turns and the car stalled on the track.
I too had to wait for a new one from Germany. Its easy to change. I had the older version of the pump without the rubber hose that tends to fail. I wanted to change out to the newer version, but it looks like the mount on the bottom of the tank is different between years. |
127k miles- original engine/no rebuilds?
|
I had my pump hose pop off. Fun stuff (it was a full tank).
Fortunately not the fuel pump itself, just the inconvenience. M |

Likely failure due to ethanol in gasoline.
Besides, the OP states that his shop says it was the pump, not the hose. After some research, I understand that the older 996 had original pumps with a short section of rubber hose. That submersible hose is only good for a few years. Posters who had split hoses and replaced it with more of the same hose had continuing problems (I have a 2005 Italian motorcycle that specifies that in-tank hose be replaced every 2 years.) Newer Porsche pumps apparently have all plastic hoses, that don't have the limited lifetime |
