Finally, removing a fuel tank on a C&C30 is possible. Just cut all hoses and wiring and remove stopcock then slide it out. After all if you're going to this trouble you're going to replace all the hoses -- right? I then had mine steam cleaned by local car raiator shop for $40CAN. Many moons ago we had a debate about wire strengthened hoses having a bit of wire exposed and to be used as grounding. Wrong!! I finally found the real reason. You can't clamp wired hose and prevent fuel leaks. Use pliers to pull wire out of hose for 2-4 inches where it goes on tank pipes. This leaves hose soft enough to be (double) clamped and the wire isn't needed since hose is supported against collapse by tank pipe. (Thanks to local chandlery expert for that gem).Applies to cockpit drain and other wired hoses too.
