New Clear Bowls are a Solution for Parker Racor Spin-on Filters

Dani Morse, Fuel Filtration Specialist

An important topic I’ve come across in the Marine industry is the compatibility of spin-on filters with clear bowls when the formulation of gasoline changes. In a recent Parker Racor article, I read that the most recent change is the 10% ethanol that has been added to the gasoline.  

“Racor has performed extensive testing using the new E10 fuel and found the current bowls retained clarity and stability, after prolonged exposure. However, it was found that ethanol concentration exceeding 10% caused adverse material changes; including loss of clarity, crazing, and shrinkage, eventually causing the bowl to separate from the filter.” – Parker, Engine Mobile Filtration Team

Other factors can also impact the clear bowls such as age, temperature, ultraviolet light and fuel additives. Check out the Parker Racor article to learn what you should be inspecting and when you should replace your parts. They conveniently give you a visual of what to look for when inspecting and list the part numbers next to the replacement bowl numbers.
