Fuel cut on hard cornering

Postby Fernand Gonzales » Wed Jul 02, 2025 19:29

Has anyone solved the issue with the capp where there is massive fuel cut during hard cornering? I take mine out to the track and have to refuel to full for every 3/4 laps to avoid this. Any solutions to this right now?

I've not heard of this issue before, so I suspect this is a problem only with your car. Maybe the contents gauge is wrong, and you have less in the tank than indicated, or there is something in the tank which moves to obstruct the outlet when cornering hard. I am reminded of the instance when someone found that a leaf had got into the tank, and was doing that.

Oh wow... how did they end up getting the leaf out? I'm wondering if it would be worth it to pull the fuel tank out, pop it open, and inspect what's going on inside.

I think they lifted the fuel gauge out of the tank and peered inside with a torch. I assume they used something like tongs to get the leaf. I think you can do that without removing the tank.

Another possibility is an intermittent contact on the electrical supply to the fuel pump, which loses contact when under lateral acceleration. I had a similar thing on my first car (original Mini), because the factory had not spot welded the wire to the spade connector, and the wire-to-metal contact could vibrate loose.

Brilliant! I appreciate this info, thank you.

Will investigate this further.
