My husband is in the process of installing 2 fresh water tanks. Can you give him some advice on how to run the plumbing. They will be side by side.
Thank you,

When replacing or servicing a tank, check the tank supports. Do they need reinforcement? How about the tank hold-down? Consider new strapping with neoprene cushioning between the tank and the straps. Finally, check fill and discharge lines. Marine engines vibrate and can cause hard fuel lines to fatigue or crack over time. Even flexible fuel lines with solid fittings can have problems.

dan is right, just pay more attention on the support.
