In the beginning... A/S used aluminum fuel tanks, then around 1986-7 began using plastic tanks. INCA was the plastic tank supplier, which has been sold to Moeller tanks 10+ years ago, which has since been sold to Teleflex, which has undergone a name change to SeaStar....Now SeaStar build plastic fuel tanks in large quantities only, and no longer has the molds for our A/S tank. I have reached out to our former aluminum tank fabricator who has also gone through ownership changes but they still have my drawings and can still build new Aluminum Tanks! Later today I will review their drawings against mine to confirm they will work, then add them to our website this week.
