Reply To: Atwood 8803LP2 Tank for Fuel Pump Conversions

Been thinking about this EPA compliant “solution” to keeping gasoline vapors out of the environment.
Attached is a photo of the manufacturers label affixed to the tank. Interesting…….
Also, embossed into the tank body in the following warning “CAUTION: Release Tank Pressure Prior to Connecting or Removing Fuel Fittings from the Tank, Fuel Lines or Engine”. This warning is easily overlooked as the embossment is shallow and the same color as the tank.
A couple things come to mind: This tank can and does build up pressure. It builds enough pressure that fuel lines, primer bulbs, and fittings could burst if they were at all weak. I can just envision disconnecting a fuel fitting and having fuel spray about, or having a line or primer bulb burst with the same result. What about removing the motor and laying it down with the fuel line still connected. The float may let fuel easily by pass the needle (in this position) and dump fuel out into boat of floor. Some research on this tank states that it is tested to 20 P.S.I.
But, I think the thing that mystifies me the most is following the manufacturers directions to release the pressure (as stated in the caution message ). Won’t that release vapors in to the air? So, what was solved? What was made more dangerous?
My advice would be to steer clear of the “auto vent” tanks.
