Catalina 270 Fuel Tank Vent (07/2016)
One of the things the pre-purchase survey called to be fixed was the
fuel tank vent.
The tank vent is the smaller black tube which can be seen going to
the through hull just below the larger black hose (which is the
exhaust).
The problem was that the vent tube goes straight down from the
through hull to the tank. This makes it easier for water to enter
the tank if the vent outlet is submerged by waves and heeling.

The space was too tight to get meaningul pictures, so no after
pics...
I replaced the ~3ft long vent hose with a new 5/8" hose a bit over
5ft long (bought 6ft and ended up cutting a handful of inches off).
This allows the hose to go up from the tank to the highest point
under the deck and then down to the through hull. At the highest
point the hose is supported by a zip tie screwed to a small wooden
block which is glued (3M 5200) to the underside of the deck.
