Default Fuel shut off valve flow rate?

I just rebuilt my fuel shut off valve with the rebuild kit from Snyder's. Everything looked good as far as the parts mating well with no burrs or gouges. While reassembling I noticed while looking in the inlet and outlet that the holes do not match up. The male part holes are in deeper than the female part holes. It's not off much but enough that it makes me wonder if it will slow the flow enough to cause problems. I'll try and get a photo but it's hard enough just to see it.

Does anyone know the flow rate through these valves? Looks like it'd be an easy check because it's just gravity flow. Does that change head pressure with a full tank versus an almost empty tank of gas? Does anyone have a new valve to look at and see if they are not perfectly lined up while new?

Probably making a mountain out of an ant hill.

Thanks (again).

It's probably worn a bit so that the plug (rotating part) goes in a little deeper than when it was new. I wouldn't worry about it, it likely passes more than enough gas than is actually needed.

You are making a mountain out of a ant hill. Even if it was half a hole overlap you would still flow more fuel than you would ever need. And it won't effect the head pressure at all.
