1996 Chevy S-10 POWER STERRING FLUID LEAKS

I HAVE POWER STEERING FLUID LEAKING OUT IN THE DRIVER SIDE WHEEL WELL ,I CAN'T RIGHTLY SEE WHERE ITS COMEING FROM,THE ENGINE COMPARTMENT NEAR THE PUMP IS DRY. IS THERE A GASKET OR SEAL THAT COULD BE BAD, THE TRUCK SAT FOR 3 YRS, UNTIL I RESERECTED IT ,THE ENGINE IS DRY ALL A ROUND THE RESERVOIR,ANY HELP WOULD BE APPRECEIATED
