You are being cost conscious right? You'll spend $15-$20 in fuel and probably walk away empty handed driving around. If its hard plastic, get creative with what you can make it out of. Rubber, probably some sort hardware store.
It could have been as simple as an oring temporarily popped out of its groove as well. Hell, that plastic ring, if it is only "cracked", fix it with some sort of silicone or even plastic weld it.
Jacks aren't too crazy, they'll deal with a lot of crap.
