Verus Engineering (Formerly Velox Motorsports) recently released a fuel door that fixes the fuel starvation problem that occurs during high-G, left hand turns. This problem is more apparent with cars that have larger fuel demands with E85 or forced induction.
The starvation usually occurs when the tank is below 7/8th or 3/4th of a tank (which is probably most of the time, unless you fill up frequently). But with the fuel door installed, you’ll be able to run lower fuel levels for lower weight and enjoy those long left hand corners.
Inside the fuel tank the fuel pump sits in a basket. The access panel for the fuel pump is under the rear seat on the drivers side. Once the fuel pump assembly out, it can be disassembled by hand, and the fuel door clips right into place with the help of some needle nose plyers.
Since we already had everything taken apart we decided to upgrade the fuel pump using the AEM 320LPH high flow pump that is E85 compatible if we choose to go that route in the future. But to install it we needed Deatschwerks 9-1010 fuel pump install kit.
All in all this was a much easier install than it initially looked. Hope the video helps any of you that decide to do this to your car.
