I originally bought a 25 gallon tank and it DID NOT have a baffle. I went back to LMC and got a 31 gallon tank and it did have a baffle. Now, the "baffle" is no where close to a stock looking LS style fuel sending unit. This is more or less a bowl that is only a few inches tall. I have let it get down to a little below 1/4 tank and it's has been fine and no starvation issues as of yet. Only 800 miles on it since the swap though too.
