I have a 2017 218 SL. When I bought the boat it was spec'd from the dealer with a 28 gal fuel tank and it only had a 6 gallon tank in it. The dealer has sent me the 28 gal tank and seems pretty easy to install once the get me the rest of the parts that is. Was wondering if I could possibly get and install drawing for this from Bennington to ensure that I install it correctly. TB please help a boater out! Thank you!!
