First, scan the NOOB guide - which is the top (sticky) post in the CRD forum:
viewtopic.php?f=5&t=54207Search down where it mentions Service Manuals and Parts Fiche, which has a link to this thread:
viewtopic.php?f=5&t=24600Which has a link to a file server away from L.O.S.T. with PDF (online) documents for the Service Manuals and Parts Fiche.
Choose the parts fiche for your year, mine is 2005:
http://colorado4wheel.com/manuals/Jeep/ ... _FICHE.pdfDownload it to your PC. I recommend getting the service manual while your at it.
Open it with the (free) Adobe PDF reader.
Turn to page 260, Figure 14-430, and look at item 20 - which (on the right), reads:
20 BLOCK, Fuel Return 05142809AA 1
That should be your item.
