I was at a point where I could starve the car on my favorite track with just 3 dots blacked out at the top of the gauge. So I'd usually fill up after every session, maybe sometimes I'd get risky and fill up every other session if the track/direction didn't involve a long right-hand sweeper. Now I just fill the car in the morning and run all day. I've finished up my final sessions south of the 1/4 tank mark multiple times now and never had an issue.

Saves time not re-fueling between sessions/classes, saves worrying about the starvation on-track if you didn't have time to top up after a session, etc.

Also, a gallon of gas weighs about 6 lbs. Our tank holds about 19 gallons, so full fuel load is 114 lbs. So that's 57 lbs gone from the car if you start your runs at 1/2 tank instead of full, or 86 lbs gone from the car if you start at 1/4 (which is doable for a 20-minute HPDE session, but any longer and you might actually run out of fuel).
It would be so interesting to have a flow sensor on the line between the OEM fuel pump and the surge canister. We know how frequently it was starving in the stock configuration.. but we have no real data as to how well our product's secondary function (of supplying extra fuel back to the stock pump) is working. The goal of that secondary function being; to help aid the stock pump from running dry and self destructing. Of course, the OEM pump will starve more as the tank level is lower. That window should be reduced by the secondary function.. but how much?

It appears we have made it through this season. But I am very curious how long you guys will be able to go before the OEM fuel pump needs replacing.
