Fuel line is in the right direction and there are two o-rings in the fuel valve, the bigger one (same as the air valve) and the teensy one at the pin end. I’d like to hear from some others about the two pins and do they protrude from the housing equally. I bet they do. All that being said, I’m still confused. Here’s my take on how it all is supposed to work and I know enough to know that I could be way wrong on this. The housing on the tank has two valves, an air valve (with the upper/left pin in the picture) and a fuel valve, the other one. When disconnected from the fuel line they shut, as they have a small spring inside. The spring pushes the pins all the way out. This would I believe prevent any fuel from leaking out the tank through the valve. When connected to the fuel line, the fitting at the end pushes against the pins and thereby opens the valves. With my fuel valve seemingly already opened, because it is sitting probably half way “pushed in”, or more, again due to my likely incorrect seating of the o-ring, by default I shouldn’t be having any problems with fuel flow. The fuel valve right now is stuck open. And the incorrectly seated o-ring is not blocking the orifice for the fuel coming up and out through the housing. Or at least it wasn’t when I did the work. I know this is a lot of verbiage and unless you have done this job before much of it might be unfamiliar. I guess what I’m saying here is – why am I having this problem? PS – I just ordered a couple new core plugs (they have a one-time use) because I’m going to take it apart again and revisit my friend, the o-ring.
