Good for you on the outing!
You did a good job of following a bit closer to the proper line on the corkscrew vs the two drivers you were following... my general advice would be, however, that you need some track instruction and that the fuel starvation is not the thing holding you back right now... just keep the tank topped off (bring a 5 gal jug or two) and you'll be A-Okay. biggest things I see are 1) not using the whole track... talk with your instructor about proper "track out" when you come off an apex and 2) steering controls are harsh, especially going through apex where g's are peak you need to be exceptionally smooth... I can't see what's going on with your feet but the brake pedal should be handled like a baby that you gently stroke and the throttle more like an on-off switch that is gradually turned on and off... I know you didn't ask for driver input, but there it is
Stuff flying around your cabin is a no-no at the track... papers and untied cables, etc can be a big deal for the car behind you or you if things turn ugly
Also, good idea to try driving with no VDC - that will help you learn faster... and Chuckwalla is just the track for it, as it has runoff room galore... just keep in mind it is easy to find yourself hooked up with another chunk of flesh and metal with VDC off so watch your mirrors especially if you spin around noob's they may not know how to respond

tl/dr keep it topped off and you'll be fine!
