If I plan on hauling more than just me, I change the pump every year, just prior to the start of the new season. The pump is fairly easy to change and less than $50. Purchace a manual and follow some simple instructions.
Yes, the dealer is correct and if you dont change the pump regularly, $500 would only cover the down payment for the damage repair."
