Does anybody experience fuel starvation in right handers?

Any update on this?
I've experienced fuel starvation on the juice in 4th at the drag strip with 1/4 tank before and on the track (and recently again at an autox) on long right handers starting at around 1/3 - 3/8 tank.

I've never had it starve but at Carolina Motorsports Park I have to keep at least 1/2 tank in it or the gauge drops below empty and the flashing light on the cluster goes nuts and I start to panic.
Seems like a real deign flaw for a 'sports' car.
So how much does this solution cost and what would be involved from a labor standpoint? What are the potential drawbacks other than weight (which does not make that much difference for me in HPDE)?
I'm not a racer but would the Spec Z rules allow it?

No updates... we are still wrapping up the 370z model. I have a lot of stuff going on here at the moment. Its an issue I am highly interested in tackling and very capable of... but I will need time to get in a better position to do it. This is something I could probably take a shot at more towards the end of the season... unfortunately. I just sort of have my hands tied here with getting anything new through the machines, but I am working on getting another CNC.
N80: You would be surprised how many sports cars suffer this issue... its very common. The way that we are doing it in the 370z ends up costing about $1000. It can be done cheaper, its just that our unit has a lot of other features integrated into it that they are having to pay for if they want to go that route. There are no drawbacks... weight is minimal just a couple pounds.
I am not sure if its allowed in those rules or not.

Any updates, I've been having this issue for years, just keep it topped off.
I haven't personally dropped my fuel tank, but what about making a 'trap-door' system. We mainly expereince this on right handers, so a small baffle to keep the fuel from sloshing left might work

Well my car is almost back together, few more parts to order and see if i have the cash to start my surge tank build. Custom surge tank, will be mounted in the glove box area, will try to build it so the glove box can be reinstalled (my car it doesn't matter) but want to set it up so weekend warriors don't lose their glove box.

I experienced pretty severe fuel starving issues today at the track in the right hand sweepers in 4th gear around 6500rpm. Anyone figure out what the best solution is?

I know some Spec Z guys have installed a 2nd OEM fuel pump into the other side of the saddle tank, just to feed the fuel back over to the original OEM pump. Been waiting for a write up/pictures for awhile now though.
