Fuel Pump Failure
My 2004 GT3 had a fuel pump failure at 5K miles and 4 years with no track time. The dealer tech said it was caused by a defective fuel pressure regulator and not the pump or hose(s) failure. The reg. blew the hose(s). All was replaced out of warranty by PCNA at NC.

As far as the "kink" in the hose. I am not sure that it is needed, the other hard plastic hose are far more pliable and pendable and i could cut it to whatever length will work to make all the parts fit nicely. I would still love to get the volvo part #, but i need to more forward to get things repaired. The Glen awaits in a few weeks.
I also realized that i did not answer many questions to a previous post. I will try to get to it tonight...my wife is away and i have the kids to myself. Those little buggers are a time-consuming and energetic handful. Which, is entirely my fault for being the high-strung spaz that i am.

Thanks for the follow up... When are you going to the Glen? I'll be there Aug 13-15 with NNJR. Will take the GT3! Got to get my roll bar, seats, harnesses done soon. Going to Pocono this weekend with PDA to scrub in R888s and get a feel for the car. Lou

Sorry guys. Its in the hands of my parts department - they are looking for the details from the last one we did. Unfortunately they prioritized this behind actual customers.

I had the same problem in my 2003 996 Cup at the club race at Sebring. I took the damage hose to the Porsche Motorsports Parts trailer and the technicians comment was, "they fail all the time". He recommend that we replace ALL the rubber hoses with teflon fuel hose like the ones on the pump. The 180 degree bend in the hose is there to keep the upper hoses from interfering with the fuel level sending unit. We use a straight hose and made sure all lines cleared. The pump is secured by a simple twist lock, you do not need any tools to remove it.

wow !!
another thing to worry about.
I was at the Summit Point event -- it was HOTTTTT !!!! (brutal, in fact)
My '04 GT3 didn't falter but maybe it will next time?
What is the feeling out there? Should this hose be replaced as a Preventative Maintenance gesture?
And should we replace it with the stock Porsche hose, or use a better one (like the Volvo one mentioned above) or what?
Does anyone know what the racing teams use? 24 hours at Daytona must put some stress on this hose, right?

Looking to do this as a PM item- don't want to get stranded!

I'd sure like to know the part number of the Volvo hose, or other hose which will fit right into my '04 GT3.
I hope someone will be able to find it out, and let us all know.

I looked for the Volvo hose and its part number for about an hour Friday with little result. It was part of a "kit" that comes with several other bits of hose and misc clamps. I just have not found the right one yet. I am no parts guy - and I just cant wrestle one of the staff away from the paying gig, but I am working on it.

Okay! I told you I was not much of a parts man... This is a SAAB part not Volvo (sorry - my bad). The hose in question comes in a kit WITH a fuel pump. But the hose in this kit that fits our cars exactly is rarely (if ever) used. Within this kit are three such hose lengths - and the angled hose is the winner.

Like I said, you just need the hose from the kit (its perfect) so talk your local vendor into just giving you the hose.
