I am in the process of re-connecting my fuel supply and return lines from the tanks to the switch and then on to the filter boss ( primary filter) and then on to the engine. The lines I had were 5/16 " supply and 1/4" return and after reading the manual, the recommendation was supply 3/8" but reduce to 5/16" prior to connecting to the engine. Is a total supply line system OK with 5/16" and a return of 1/4"?
Thanks in advance for your advice/recommendations.
