Yep it is a very known problem - even on units that should be good according to DMCH's supplier (such as mine). But you don't need to buy such an expensive check valve. Unless you want to be adding an external in-line check valve later, then I suggest doing it when you install the pump/sender combo, if not for anything more than insurance.

Here's the one that I just ordered - $14 including worldwide shipping, ships from Memphis, TN:

Or, you can get the $8 plastic unit, including worldwide shipping, ships from Miami, FL:
