A must. Chrysler said not to worry, they didn't include it in my $65,000 2500 Laramie. But every time I've checked, there's water in that compartment, and some of it should go into the fuel if you don't have a cap. Water in the fuel/filter system is bad for you, but good for the dealer who charges you $$ to fix a contaminated fuel system...
