Yes you can buy seals for these - they're about 12 dollars. Honestly, it's not worth the time and effort you'll go through to wrestle the seal out and back in without damaging it. When I was faced with this same problem on my 95 F-150, the reman'd replacement pump from Advance only cost $34.00. I thought it was much better to renew EVERY seal in the pump at once, don't you think? I like Ford parts, but I have had good luck with my aftermarket P/s pump. Be sure to borrow the special tool for removing and installing the pulley - they bend easily if you don't center the extraction force on the center ring. Good Luck!!
