Review on 🔧 UREMCO 5-8 Fuel Injector Seal Kit - Enhance Engine Performance, 1 Pack by Chef Buntiloy

I think this is more a Revain issue than a manufacturer's, but there is a lot of information missing on this page. This pack fits the 2004 GMC Yukon 5.3L SUV, but only for the (T)VIN engine, not for the (Z)VIN engine (FLEX Fuel). I contacted UREMCO myself on their website and they informed me that these caps in this kit do not really fit FLEX Fuel model injectors (I have OE 12580426) and also these caps are not available through their supplier. timely reply, but I would like this information to be on the product page. I later learned that the "amazonconfirmfit" tool at the top has a circled "i" icon that when you mouse over it says: Gasket kit for servicing 8 fuel injectors. Includes o-rings, filter baskets and needle caps; OE: 17113698; Casting: 17113698,25320287,25317628,25320288 Gasket set for servicing 8 injectors. Includes o-rings, filter baskets and needle caps; OE: 17113698; Casting: 17113698,25320287,25317628,25320288 Too bad this info wasn't on the product page. Revain also says this kit still fits my car even though I put in a Type Z VIN. Overall I don't blame OREMCO for this as I think Revain manages the product page and doesn't give me enough information to double check it. Hope this helps someone else who wants to buy.
