I guess I'm used to the four strokes setting an inch and a half off the firewall. You will be OK, but use the retainers I mentioned before. Let me know if you need a photo of what I'm talking about.
A couple points, don't tighten the bung (lid) to tight as those ARF tanks tend to split open some times. Also, make sure you don't have sharp edges on the brass tubing that could cut the lines. You will not have much luck trying to replace the lines later without pulling the tank. Use some wet or dry and round the edge just a bit. Then make sure you rinse the tubes out with some fuel to get any grit out that may have collected, then install them into the tank.
One last thing, I usually use a short, 1/4' to 1/2" piece of fuel line on the vent tube inside the tank. Just a bumper to speak on the tube so it doesn't have a chance to abrade the top of the tank.

Thanks Don. I could use some pics if it's not to much of a bother.
I sanded down the sharp edges on the brass tubing to avoid cuts in the fuel line already.
I'm not sure about what you are talking about or how to do it on the vent line. How would that help and don't you run the risk of cutting off the vent line with tubing on the end of it?
