Shouldn't *need* a gauge that goes higher, unless you are boosting the engine somehow. If you're after better accuracy, a gauge is most accurate in the middle of it's range, but with 0-100, you lose resolution. But, in reality, an engine with a vacuum referenced fuel pressure regulator will have pressure from 33-44 for normal settings, which is about 50-75% range on a 60psi gauge, and you'll be able to read it easier, and not be too far off on accuracy. Most aftermarket gauges for fuel pressure aren't worth much for accuracy anyway, though.
In short, get the 60.
