HPFP and Low Gas

So I got my 335i less than 3 months ago, and this week is the first time I've had the gas level below 1/2... and guess what? It's the first time I've heard it take a while to crank. Only 1900 miles on it so far.... think this whole KEEP YOUR GAS LEVEL HIGH thing has any merit?

One long crank could be anything. Literally. Don't try to over analyze. Just enjoy your car when the time comes it will come. I had long cranks for a couple weeks and they went away, it could have been anything. Hope all goes well sir.

I doubt this has anything to do with the HPFP, as there should still be fuel in the lines. There is a low pressure pump in the tank, but upon startup the fuel used is already "out" of the tank if that makes any sense. There is a belief to keep your tank at least 1/4 filled as the gas acts to help cool the pump, though I'm not sure how much merit there is to this either.
