Great customer support from Autool if ever needed. ### ⭐⭐⭐ Missing GM LTx GDI adapters, had to improvise. UltraSonic cleaner has no heating feature. *by E***R on July 9, 2024* For GM LTx platforms there is no proper adapter, you have to find a fat o-ring to take up the space to the nearest adapter available in the kit as the OE o-ring is too small. Ultrasonic cleaner I thought came standard with a heating element, it does not. Also, GDI injectors run well over 1000Psi; this can only go up to 80-100PSI so while it can measure rate at low pressure there is no telling how much volume is used at it's original operating pressure. For the proper GDI tester runs several thousand dollars. For traditional injectors it works just fine. ## Frequently Bought Together - AUTOOL GDI Fuel Injector Cleaner & Tester 110V Ultrasonic Wave Fuel Injection Leakage Tester 6-Cylinder Automotive Fuel Injector Cleaning Machine - NORTHWEST ENTERPRISES Ultrasonic Cleaner Solution for Carburetors and Engine Parts, Ultrasonic Cleaning Solution and Washing Compound for Ultrasonic and Immersion Washers - Concentrated (1 Gallon) - Master STAGES CLEAN2020/1G Clean 2020 Washing Compound for Ultrasonic and Immersion Washers, Pale Yellow, 1 gal Jug, 128 Fl Oz (Pack of 1) --- ## 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.tn/products/454499162-autool-gdi-fuel-injector-cleaner-and-tester-110v-ultrasonic-wave](https://www.desertcart.tn/products/454499162-autool-gdi-fuel-injector-cleaner-and-tester-110v-ultrasonic-wave) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-13*
