Product Details
Fuel starvation fix for F80 M3, F82 M4, F87 M2, as well as F30, F32, F22 N55/N20 models.
Not for cars with N51 SULEV engine.
Fuel starvation on the F80 M3, F82 M4, and F87 M2 occurs when fuel level drops below 1/2 a tank and g-forces go up. The problem is worse on right-hand turns. The factory system simply cannot pick up any fuel to supply the main pump. Our solution came from our GTMore program and adds a second main pump to the system. With this kit we were able to get below 1/4 of a tank before experiencing starvation!
The problem with the factory system is that it only has one main pump (on the right side) and then one small suction tube for the left side of the tank. In a hard right corner where the fuel sloshes to the outside the suction tube is no longer drawing in fuel and the overall fluid level is too low for the main pump to suction. As a result you get a hesitation or stumble mid-corner.
Our solution to F8X fuel starve situations is to position a second pump on the left side. The second pump is installed through the access panel for the main pump - there is no access panel on the left side. The install is straightforward and simple, however, requires a small modification to the original main pump frame (a hole) and some minor wiring. You also need the rear seat and side bolsters removed for access. Power for the new pump comes from the fuse panel under the trunk floor. All wiring plugs and connectors are included as are detailed instructions. Installation should be done when the fuel tank is very near empty.

Bought the Infinity Design S65 Modular Carbon Plenum for my E9X M3. The finish is excellent and it completely transforms the look of the engine bay. It feels like a properly engineered piece rather than just a cosmetic upgrade. Really pleased with how it looks once fitted.

I went with the Endless MX-72 Plus Brake Pads for my G8X and they've been a great upgrade. The pedal feels positive and the pads give plenty of confidence when braking hard. They also work well for normal road driving, which was important to me. CPC Clubsport made the whole ordering process easy.

Had the Nitron NTR R3 Coilovers fitted to my E9X M3 and the difference is impressive. The car feels much more controlled and planted, particularly through faster corners. The adjustability is a big advantage as well, allowing the setup to be tailored to how I use the car. Excellent upgrade for a car that sees both road and track use.

Fitted the Ferodo DS1.11 Brake Pads F8X (Front) to my F82 M4 and they've been excellent. The initial bite is strong and the braking feels much more consistent when pushing the car hard. They’re particularly impressive on track where the brakes stay predictable through repeated heavy braking zones. Very happy with the purchase and service from CPC Clubsport.
