Nope, that place doesn't have it.
AllDataPro at my library has very little on it for jeep parts. Some illistrations but very few "blue" highlighted numbers that you can click on and get the part numbers. I'm surprised I can find more Mitsubishi parts than Jeep.

Some folks on Mitsu tech have programs to go on that can get part numbers. Is there anything like that for Jeep???

I went to a junk yard today and all the 94+ Grand Cherokees had this same tank , both 318 and 4.0. They were all crackeked. Ozone in CA air kills plastic pretty quick.

Thanks for all the help. I have emailed a couple Jeep dealers with no responce.
