Guess is was my turn.. 25K miles and it finally let go... Won't start, had to get a wrecker to drag me back to the shop... There just isn't anyway to look cool on the side of a busy road broke down in a TT for nearly an hour..... Confirmed what I suspected today and it's the fuel pump... It's days like yesterday that push the boundaries of my love for this car...!

 

Its a Pi$$er , sorry to hear that.
Any chance once you find out, posting the exact failure...pump pipe split or mechanical failure etc.

I'm on my 2nd replacement. 21k miles total on the odo.
New one doesn't have any "rubber" hose to split.

 

I will post pics of the failed pump when I pull it out.

 

Is this a common problem with 996 Turbos? Never experienced a failed fuel pump with any of the cars I've owned. 35k miles on my Turbo, and as far as I know, still on my original fuel pump (knock on wood).

 

yeah it's the line that develop leaks, the fuel pump is still good but to buy the line at the stealership you have to buy the fuel pump assembly...

 

My fuel pump failed recently and I changed the split hose with a similar one and the car runs fine now.

 

There's a silicone hose some of the cup car guys are using- the one rubber hose is the one that fails. I'd like to replace it with a silicone version as preventative maintainance- but I'm not sure where to find it...

 

are the replacement pumps a 997tt part? Also, what is the best source/price for these?

 

This can happen to any make of car, Porsche included. I think the overall number of incidents is low but you see it reported here so you may think it happens more often than it does.

 

Is it the brown hoses in this pic that are splitting ? If so why cant just the hose be replaced with any fuel resistant hose rather than paying $$$ for a complete new pump unit. Also does this seem to happen more on cars that have been run on race gas?

 

The way I understand it, the brown hoses are the ones that do not split- it's the rubber hose on top of the pump that fails. What you need to do is replace the rubber hose with one similar to the brown ones, which from what I understand are silicone. There's a thread in the 996 GT3 forum over on rennlist.

 

Sorry for the quality of the PIC's... Still trying to figure out this whole camera thing. Bottom line: The part cost me about 600 and about 2 hours of time. I may have been able to complete it faster but I started drinking beer and watching BB.... So I wouldn't use my experience as an example. The hose split..

 

i had the exact same thing, did the new unit had a rubber hose or was it all plastic?

 

Nope. The new one had the white plastic pipe instead of the rubber fuel hose. I am not sure but I suspect there are some of the old pumps still floating out there as new stock... I assure you that it's only a matter of time your pump WILL FAIL sooner or latter if you have the old style.
