I’ve found that prices for fuel filters can vary widely. While I always aim for quality, I also keep an eye on my budget. It’s worth spending a little more for a filter that offers better performance and durability. Always compare prices from different retailers and consider buying in bulk if you have multiple boats or engines to maintain.
