It is beautiful in design and fabrication-
Ah Haaaa!.
The larger hose taking off at a T valve from the vent line thru the aft fuel compt. bulkhead = a solution to Mstr Huang's port cabin side vertical run of 6-7feet of crimped vent? Master Huang had very good wood worker's.
The wired disc could be a tank tender?
Thankyou for the picture.

Smile and they won't know which question to ask.

You have answered the question why Master Haung created a 3/4" limber hole in the lower aft face of Pamarno's fuel tank compartment!
 Recent surveyors felt this should be a contained area in light of newer environmental concerns about fuel spillage, it was viewed from a different perspective in the 1980's.
 
My 25 gallon tank was also on teakwood battens, that I re installed as they were just fine, also the 27 year old tank was not in need of more than a power wire brushing and cold galvanizing coating and Hammeral. I also recoated this compartment with bildge paint.
The interior of the tank and welds were sound, although a 1/2 inch of sludge dirty with grit and goo lined the bottom and was slightly above the supply lift tube. I cleaned up with a spill diaper and thoroughly washed down with alcohol solvent, let dry and vacumned any remained dust. I found butyle gasket material (via a local Marine Diesel service CO, in Bellingham,Wa) and cut&punched for the faces and bolts on the inspection lid. With new lines and an in line 12volt fuel lift pump for easier oil changes on the Volvo Penta MDIIC, I have respected the diesel gods.

While I've believed that, about Baba owners, "there are those who have replaced their fuel tanks and those who will", after seeing OWTW's tank out of the boat, this is a much bigger "Master Huang surprise" than I expected. Please look on the forum's maintenance section for the pictures. The executive summary is that, at least in our '85 35, there are three glaring errors:

1) There is no drainage for water trapped along the sides of the tank. There is some space for water to eventually leave but that's not the same as proper installation. At least on OWTW, the tank was killed by water standing, albeit briefly, along the lower edge of the tank.

2) The tank rests on two rails or stringers (mad! e of gl ass matting over PVC pipe or hose) and wood blocks under the tank. A full 60 gallon tank probably weighs close to 500 lbs (480 lbs for 60 gal. of water, diesel is slightly lighter, add the weight of the tank and... 500 lbs isn't hard to reach). Setting it on the stringers and wood blocks that will over time turn to pulp due to water intrusion... not good.

3) The tank is held in place by cleats screwed to an aft and forward bulkhead. There are no straps or other hold-downs. On OWTW the forward bulkhead was rotting to the point of not longer being servicable. The tanks was ultimately held in place more by rust than anything else.

The tank walls are about 1/8" thick; rust had reduced this to about half (1/16") in at least the point where the tank was cut apart. The prudent Baba owner would do well to check their tanks for rust problems.

Cheers,

Rick
