After being told some months ago by my indy that my Tandem Pump was very very corroded and needed sorting I started to look at the issue.
After reading many reports of the Pump that was made by Pierburg rusting as the cover was made of mild steel but due to the location low on the back of the 997 they were corroding. I then read about a replacement stainless steel cover made by 9M so managed to get hold of one , sadly although a good idea due to the molecular differences in the metals used the Stainless steel cover was getting affected by heat etc and causing the pump rotors to contact the cover at best causing a rattle and at worst breaking the pump.
a very disappointing outcome, so it seemed the only option was to replace the pump like for like knowing that over time the same would happen again.
I realised I could paint it with hammerite or similar but a bit of a bodge fix for such a stunning car.
I then looked at the price of the Tandem Pump from Porsche and found that depending on where I looked they were anything from £400 to £500. So first thing was to find the pump directly from Pierburg and avoid the Porsche tax :wink: I read that the BMW1 series used the same pump which although came from a German company Pierburg was infact made in Italy.
This set me off looking at European parts suppliers I found one that was listed for the boxter etc. but not the 997 so I contacted the company who are called Autodoc, they confirmed the item I needed which was Pierburg pump number 70026402
their regular price was £297.99 which was between £100 and £200 cheaper than Porsche. they offered me a discount which took it to £275 delivered from Germany.

Whilst I was doing this, I read about a company who after much research had found the issues with the Stainless steel replacement covers and decided that the optimal solution was to create a Stainless Steel over cover.
Well for me this was the perfect solution as there was no more risk of the pump getting damaged by contact with an aftermarket part, but a Stainless Steel cover to look good and protect the mild steel cover for the future. Due to similar material and manufacturing costs logically this over cover was going to cost similar money to the old failed 9M stainless steel cover this made sense and at least would be a good long term fix.
Therefore the key for me was finding the tandem pump at the right price, as the Pierburg pump from Autodoc and the new Stainless Steel over cover were going to cost me similar to just the pump from Porsche.

Today I received my new Stainless Steel over cover, I was very pleased with the fit and quality ,I was also happy to see it came with 4 large and 2 small replacement Hex bolts this was an unexpected bonus for me as the pump had been supplied without the new Hex bolts and they seemed to be a couple of pounds each from the OPC when I looked quickly.
I am very pleased at this outcome as it offers me and others like minded a decent long term fix for a known issue. There is also no reason why anyone with a non leaking tandem pump can't grease the cover up and fit one of these Stainless covers to protect the existing pump and at minimum extend the life and reuse the stainless cover when they finally need to replace the pump.
Just need to get it booked into my Indy now to have it all fitted.
I have taken some photos so you can see the pump and the Stainless steel over cover .
