Remove Fuel From G23

[blueroom]

I want to remove about 20 gallons of fuel from our G23. I thought I might be able to get a small hose through the filler and siphon it out, but there must be a second anti-siphon down closer to the tank.

What the easiest and least invasive way to get a hose into the tank t remove fuel?

Just a guess, but I would try to find where the vent / overflow line connects to the top of the tank and remove the hose fitting. Should then have direct access to the fuel tank with little risk of spilling since the vent is positioned at the top of the tank.

There is an anti-splash valve between the fill and the tank inlet. Mine is a fairly simple design with a "flap" that is spring loaded..... so if you did it right you could get a small hose thru it to siphon but the hose needs to be rigid enough to manuver thru that flap yet flexible enough to make the bends required.
You could expose the fill hose (on my boat there is a panel in the rear locker against the back of the seat that exposes fill hose), then remove the fill hose from the bottom side of the anti-splash and do it that way.... or disconnect the fill hose from the gas tank.
If you remove your floor, you could remove one of the vent lines as suggested, you probably have more than 1. My boat has 3, 1 near the rear, 1 at center and 1 near the front. I have never removed one of my vent lines but assuming its similar to replacing a fuel sender, just be careful to properly torque the nuts holding the gasket in place so you don't have leaks later.

Curious what you did to solve this issue. I need to siphon bad fuel ASAP and I was looking at what appears to be a vent valve. (Image attached)

Like posted above it is a pretty simple flap, you should be able to get past and siphon out easily enough. I would think.
