I'd say it was still good since it would be restricting the fuel flow. If you have 40psi at the rail, it should at least start. It's good to replace them every so often, if they do get a little plugged it makes your fuel pump work harder. It will cause it to fail much earlier, but that's just regular maintence.

Gas in the oil just isn't good for the internals of the engine. It's not a lubricant, so I imagine it would shave years off the life of your engine given it was driven like that for a long time.
