Hi Rennlisters,

My high pressure fuel pump on 997.2 Targa died => I took the car to the Porsche Center for repair. However, the problem is that the Porsche Center apparently does not have any HPFP on stock and they don't know when it can be available. They literally told me: "look, the supplier (which I understood is Porsche's "Central Warehouse" in Germany) is telling us that the delivery of the pump to us is currently without the time guarantee - it can be tomorrow or it can be in one year, we don't know, maybe they have to manufacture a brand new one". I am already waiting for like 1.5 month and pump delivery date is still unknown.

I started to look elsewhere (non-authorized repair shops) and everyone is telling me that they are able to get the pump in 2-3 days. I assume it is an aftermarket.

How would you proceed here? Is it worth waiting for the "original" pump from Porsche or is it ok to install aftermarket pump? What should I ask the repair shop / Porsche center?

Thanks!

I don't have data specific to this pump, I have dealt with parts shortages from Porsche. So... I would not assume the alternative suppliers are aftermarket. When the supply starts to dry up, you can find Porsche parts from other sources. Further, I have purchased non-Porsche labeled parts that are really the exact same thing from the same makers (AKA OE or OEM). You need to do more research. Another alternative is to buy from the UK or other Euro market... you will pay more, but you may be able to get exactly what you want. Check eBay. Check FCPEuro or Pelican... they tell you if the part is original, OEM/OM, or aftermarket.

These supply issues are nuts... I really don't know what is going on but something really wacky is going on. Fuel pumps are go/no go parts for operating our cars and for Porsche to let these disappear is really wrong no matter how you look at it.... particularly when Porsche brags in adverts how many of their cars are still on the road.

Let us know how it goes.

Milan, while I have no definitive answer to your dilemma, I can with most certainty assure you that Porsche does not manufacture the fuel pump. I would be very inclined to assume that it's probably made by Bosch and it's probably also in use by Audi and maybe even VW.

Like I said, not the answer you're looking for but probably another venue to take a look at.

My HPFP was failing, so I used a Foxwell NT530 to confirm pump pressures vs the fuel pressure demand.

I bought a "new" HPFP pump off Ebay, I can only assume it's a rebuilt item.

I DIY fitted it in 2020, the new HPFP transformed the car's performance, The engine or pump have not missed a beat since.

Be bold.

Thanks guys for the replies - highly appreciated. Alright, I will see what I can do here

Unless the car is under warranty and they're giving you a loaner, I wouldn't be taking it to the dealer anyway - higher labor prices and from what I've seen shoddier work with less care that they've done shoddier work. If FCP Euro shows one on their website, buy it from them, have it replaced at a respected Indy mechanic and the part will be guaranteed for life coming from FCP so you'll never pay for another one.

Hi everybody,

so I finally managed to get the new pump. Took almost 4 months. They are simply not available.

However there is a new problem After the pump change, the car ran ok for 1 day. And the very next day when I turned on the keys, the car started to behave weirdly - after the start, the engine was shaking, rpms were dropping out of nowhere, the car was jerking on the road and after some time, the orange engine light started flashing. So we turned the engine off, waited and tried to turn it on again. And suddenly the problems were gone - the car was behaving ok. Quite a scary situation. Now we will try to diagnose what is wrong - again :/

You need to read the codes. Stop off at an autozone or other parts store, they will read for free.

It could be just a coincidental failure of an ignition coil, or related to the pump... codes should tell you.

We took it to the mechanic and the code reads: misfires on cylinders 1, 2, 3. And the O2 sensor is throwing error (this is a long term issue with the car though).

Today, we took the car for a spin and it was behaving ok - start was ok, ride was smooth, no problems on the road...

Which pump did you replace it with? Link us here so we know

The part number: 9A111031507. It was taken from another car' engine (not sure if 997.2 or 991.1).

Nothing wrong with a Porsche reman, but don’t trust aftermarket remanufactured. Haven’t ever seen good luck with any aftermarket remanufactured fueling component

Why buy a remanufactured one with a core charge when you can get a new one for less money? I ordered 9A111031507 from Gaudin in Las Vegas first thing Tuesday morning - free shipping $1,240. It went out Tuesday afternoon and was at the shop Thursday afternoon. It was cheaper from Delaware Porsche, but I dont know if was on the shelf. I called Gaudin and was told it was in stock.
