I would simply call the race shops in your area that have 997 Cups running out of them. Or call the big guys, farnbacher, Kelly Moss, TRG, GMG etc... They all certainly have 997 Cup factory fuel tanks sitting on the shelf for car they replaced them with fuel cells. I know I have one on my shelf and there is at least 1 other from a 2006 on the shelf at our shop in California.
If anyone in Calif. wants to buy mine I will check on pricing from PMNA and give you a number (substantial discount to new). What I can't tell you is if it will work, so you should figure that out first, as I don't want to sell it to you unless you know you can use it.

This is correct - the Euro tank is 90 litres and the USA tank is 64 litres and the smaller size was for the C4S and Turbo, since the 4wd system interfered with the larger tank. Porsche got DOT for the wide body with the smaller tank, so the car had to come with the smaller tank. They did not want to go to the expense of certifying 2 tanks (I presume).
The Cup car tank is also 90 litres and may be the same as the ROW tank for 2wd cars. 997 Cup car tank is part number 997.201..013.90 (R). The R designates it as a race part, so you can only buy it from PMNA or Porsche Motorsport in Germany. But the part numbers may be the same. Attached are details on the 2007 997 cup fuel tank and related hardware.
In the 996 variant - I put my 996 Cup tank in my 996 GT2 and it was an easy fit. No installation issues. I presume the 997 would be similar.

So my RS is going in for some race parts to be installed. I really want to add the CUP fuel tank while it is at the shop.
Anybody know if it will work? Cause im ready to do it.
(i want the larger tank for targa rallying which is full of long transit stages)

Fuel gauge readings due to tank changes
Please excuse me if my question below has already been discussed.
How will the larger "Cup" tank affect the reading of the fuel gauge in the US spec street car?
I assume that the gauge is calibrated for the 64 liter tank and the sender, ecu, computer is not going to know that there has been a change unless it is re-calibrated.
Has anyone addressed this issue yet?

My RS is at Werks II getting the 90L tank installed this month. I will keep you posted on the outcome.
I bought the tank for $375.00. It was removed from a 997 CUP from new. The CUP recieved a fuel cell the day it landed in USA.
The CUP 997 tank and Euro 90L tanks are the same.
anybody want my old tank?

My understanding is that the smaller tank in our cars is due to a regulation which stipulates that the tank has to be some distance behind the front axle. No technical reason, just an arcane regulation. Race cars are exempt since they are not street legal and don't have to meet the same rules.

tcsracing1 question
I suspect the fuel tank sending unit determines the position of the pointer on the gauge. If the sending unit is half way down, the tank is half full and that's what registers on the gauge.
