I’ve got an Irwin 37’ CCKetch, the diesel tank is glassed in under the salon floor. I need to inspect the tank so I am thinking of taking a jig saw and cutting in an inspection port. Is this sane? Will it help my to clean the tank or is the tank divided up by baffles to subdue rolling?
I bought the boat 10 years ago - it had sat unused beside a barn in Maine for 17 years with its 100 diesel tank nearly full. Oddly, the fuel turned out fine but with such a large tank it takes me a few years to use it ( it stops feeding the fuel line when I get down to about 15 gallons left. )
Anyway, I changed my filters recently and found so much gunk in the racor secondary filter that I was compelled to remove it, disassemble it, and clean it. I’m sure there must be gunk like that in the bottom of my tank. Oddly as well, the filters need to be changed only about every 90 hours ( for me that’s about 3 years). I have not had clogging problems.
The one exception is that last week there developed a blockage in the line coming from the diesel tank to the racor filter. I just blew about 90lbs if compressed air through it and things were fine again. That was the first and only time I’ve had that problem in 12 years of running the engine. (A VolvoPentaMD2040
Any ideas on inspecting and cleaning the tank?
Thanks
