Clear 14 gallons of wine? That's a tall order. However ...
First of all, you need to have a rough idea why it's cloudy. That could be a) it hasn't finished fermenting (but I assume that it must have by now), b) it still has peachy bits in it, c) as you say that you used probably too many peaches, you may have a pectin haze, or d) any permutation of the others.
If it was purely a haze, it would probably have gone straight through your filter rather than clogging it up - it's a good bet, then, that suspended peach flesh is at least partly to blame. In which case, you need to get the wine as cold as you can (short of freezing) for a day or so. That will stop any thermal movements in the liquid dredging up the sludge and most of it should fall to the bottom. Then - very gently - either syphon or jug the wine from the top into a new container via a strainer (a couple of layers of muslin in a colander will do the trick). It would be best to include 5 mg per gallon of sodium metabisulphite (Campden tablets) during that transfer, but it's not a must-have if you really are gentle.
That process will result in a clear wine, a less murky wine, or it will make no difference at all. If it's clear, Sally's your Aunt. If it's clearer but still not see-through, the problem was partly caused by pectin. If it made no difference, pectin was totally at fault. This is where I tell you that you used the wrong enzyme. Amylase digests starch (and I assume there were no starch sources in the recipe?). It's pectolase which digests pectin. If you have any of that, you should stir some into the strained wine. Had you done that at the outset, the dosage would have been one level teaspoon per gallon. With all the alcohol now in the wine, the dosage goes up to two level teaspoons per gallon - rather a lot of pectolase. However, peaches aren't a pectin-rich fruit, so you may get away with the one spoonful dosage. You could then try to filter again (rather than straining) - you may just get a further improvement, although you also increase the risk of oxidation if you haven't dosed it with metabisulphite.
So - lots of pectolase or a hazy wine. A pectin haze never hurt anyone. The wine, as long as you've strained out residual solids, will be perfectly good (and a glassful of wine is intrinsically more translucent than a huge container-full). It will taste as it should and have the requisite desirable side-effects. Whatever you do, don't throw it away. If you can't bring yourself to drink a hazy wine (although I recommend that you make the attempt) then it's good for cooking, making jellies, preserving ... ermmm ... peaches, for instance, or even leaving some of it exposed for a few days (better in summer, though) when you stand a very good chance of creating a very nice white wine vinegar.
I still suggest drinking it
Let us know how you get on ...

EDIT: GA's suggestion is sound - I assumed that you'd tried that, as you said you'd fined it???
EDIT 2: There is always the possibility that it will clear itself with time - but it's only a possibility. Some wines do have stubborn hazes that just disappear after three to six months. Don't hold your breath.
