Jay. Just finished installing the M3 baffle as per your link. My AllData was very vague on the fuel pump R&R, & your pics helped a lot. Really didn't take more than 1/2 hr, but installing the rear seat was a pita. It didn't want to clip into the front latch points. That took me about another 1/2 hour b4 I figured out what tricks to use. Anyway, no big deal, since my lead tech is much bigger & burlier than me & I know that it would have taken him 2 min to clip the rear seat into the brackets. I just didn't wnat to hear him razz me on such a simple procedure. Big guys generally win. Hopefully, this baffle will help me get me thru the entire track day on Wed with no fuel starvation. Will keep everyone posted that contributed to my thread.
Jay, Thanks for the pics & diy. Chas

No prob dude! Good luck Wednesday hopefully it works for you like it did for me. Please post an update for us. You going to Monticello for June 7-8?

My M3 did this coming out of the carousel turn at Barber Motorsports park as well. The line was about 3/8 of a tank, so that's about all the help you'll get from the baffler.

To expand the record, I have experienced this at both VIR and Summit Point Main. I have a 330i ZHP sedan, and it occurs around 3/8 tank. On both tracks it happens out of Turn 1 coming off the main straight. At Summit Point is does not happen at 6a/6b, which is also a long right hander - almost 270deg. Maybe the hard braking coming off the main straight is a contributing factor. 6a/6b comes after hard braking into a left hander at Turn 5.

Anyway, thank you e46fanatics for the wisdom. Looks like I need to order an M3 fuel baffle.
