Life expectancy of aluminum diesel fuel tank
I have an Islander 30 built in 1974. The tank is original and does not leak at this time. The tank has had a cleaning/inspection port installed in the top but the rest of this 30 gallon tank is glassed in place under the starboard quarter berth. The tank has some some issues in that the main feed line to the engine is connected to what used to be the return. What used to be the main feed with the fuel cut off valve still attached has no siphon tube connected to it and now only serves as a return.
My question is: Should I attempt to repair the plumbing on a tank that is this old or should I be thinking of replacement ?
Thanks for your ideas.
