Run directly into fuel lines on top of engine. Make sure to include the return line to your cylinder. My 02 Duramax took over 1 1/2 hrs to burn thru mixture. DO NOT put the cleaner in your fuel tank!!! Works great! **Q: Can you use this to put directly into the cylinder to free piston rings? If so, how should it be used? How much, how long, etc.** A: Spray some WD- 40 into cylinder to free up piston. **Q: Can I put this in the crankcase?** A: this product is for cleaning fuel system not the oil system I would NOT put in crankcase **Q: ?The product show is no longer avalible under this part number its now sold as 19355198 it has new packaging and pricing old stock is still ok** A: Do not know about this. I do know the Genuine GM Fluid 88861803 superseded the 88861802, and I have not sought out any lately as I have two bottles of the 1803 left from several I bought. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/11905714-genuine-gm-accessories-88861803-upper-engine-and-fuel-injector-cleaner](https://www.desertcart.jp/products/11905714-genuine-gm-accessories-88861803-upper-engine-and-fuel-injector-cleaner) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-04*
