Pacific Seacraft is in the process of conducting a total refit of my 88' Crealock 37 and all systems were replaced. Without doubt amongst the most needed items to be corrected was my fuel tank. We used the John Justin original tank instead of the new fiberglass PSC tank as a result of the cost and the decreased capacity in the fiberglass tank. The new aluminum tank was prepped for a zinc based paint to prevent the break down of the metal due to the sea water potential in the bilge. Also, the keel bolts have been rumored to be a problem because of the disimilar metals. We fiberglassed some stops between the keel bolts for absolute protection from the two metals reacting. The end result is a dependable and permanent solution with a total cost of around $1,000 and the fuel capacity unchanged. Good luck!
