[AT] Gas can rant

[charlie hill]

I'd be looking for some sort of pressure relief valve.

I don't know how many of you use outboard motors but the new gas tanks for
them are a nightmare unto themselves. The standard tanks years ago used to
be metal, 5 gals and had a pressure vent built in. Then, they went with
plastic, six gallons and had a thumbscrew on the cap to open to vent. Many
a boater set out from the dock only to have their engine die because they'd
failed to open the vent and the motor starved for fuel when it reached a
vacuum in the tank. Now, due to EPA regs they are 6 gals with no vent
whatsoever. If you leave a tank in your boat in the sun, it will swell like
a balloon and worse, the pressure can over-ride your floats in older motor
carbs and pump gas out in the engine.

Happened to a friend recently and he called Atwoods tech support (Large
manuf. of these pony tanks) Tech support guy said to call and thank your
local EPA office and by the way, Atwood sells an optional fuel tank
pressure shut off valve for 20.00 to put in the line before the bulb to
stop pressure from the tank from reaching your motor. (It is simply a fuel
safe ball valve). My friend said "So even if I have this valve and my tank
swells but my motor doesn't leak, what do I do?". The guy said, "you open
the gas cap slowly to relieve all the pressure then open the valve". So,
the EPA is so smart they require a no vent tank that has to withstand 5psi
of vapor pressure which can only be used by opening the cap and venting all
the vapors anyway.

Stupid, Stupid stupid.
