Fuel system check (suggestions ?)

Although the color is black or brown rather than red or "other", the crack case vent line can add small amounts of oil into the bilge if it is not connected to a collection bottle or the air filter ...

As far as checking the bottom of the tank for leaks, there was a 1X4" board across the edges of the two tanks on my boat, poorly secured, fuel and waste tanks. Remove that board. Try to get your hand in between with a clean white paper towel. If not (probably not), get a skinny yardstick and tape a clean white papertowel securely around the end. Keep it thin and clean. Then, insert in between tanks as a "probe." Any red color extracted? If not, nove it over a bit and try again. Hopefully, no fuel there, especially foreword, inboard corner.
I assume the 1x4 is visible after you remove the board ( about 2’ x 6’) under the berth that is screwed down ? There are also teak trim strips around left right edge that might have to be removed. If there is a leak , I’m wondering if it is cheaper to find a shop that fabricates tanks to just make me a new one with additional inspection hatch, quality fittings etc . Have no idea how much it would cost but I should probably triple my expectations. $1000 -> more like 3 grand :)

A few years ago I had a new alum. fuel tank fabricated and it was way under $1K. If you have a decent drawing, contact the folks at
I had a baffle installed, two good sized clean out ports, and a new gauge sensor.

Yes, your assumptions are correct. Remove board under settee cushion and trim board. That to board comes out but is a tight fit out the companion way. then you will see the 1X4", I think.

Here in So. Cal, go to Berry Marine Fabrication in Santa Anna for a new tank. Best if you take him the old one but that is not necessarily a requirement. Can work from your dimensions or actually may have the original Ericson Blueprint plans for the tank! He has many of those! It is run by Vic who is a one man shop and does great work at a reasonable price. I hope he hasn't retired! Here is a link with phone & address info. Less than $500 for mine about 6-7 years ago. Included a new fuel sending unit and was beautiful work done.

Another useful thread on this subject:


There is one post in this thread which suggests using epoxy to seal a leak (likely a pinhole) after thorough cleaning of the tank interior. It might be a good option but would probably necessitate cutting a new inspection port and installing a gasket and cover over it, ala Christians efforts.

One thing to keep in mind is that the OEM tank may or may not be best fitted to the space in the boat. When I replaced our stock tank, I was able to go from 14 gallons to 19 gallons and install the new tank in the same place.

Welcome aboard, Luther.

You need to fill out your member profile with boat model, year and engine. Such information is necessary for informed responses as there are a lot of Ericson and Olsen models and the year manufactured counts a lot for troubleshooting.

Then click on your name and add the information to your Signature line, so it will appear under each post. Username/Signature.
