Be gentle with the pipe when pushing it on, bit by bit. Little bit of plastic burring might want trimming but its nothing to worry about.I thought at first it didn't fit, the O rings are slightly larger than original. Remove the E clip first, remove old connector. When inserting new one use something to push the top down, i used pliers and leaned my weight on them and you can feel it drop in. Replace e clip. Then carefully connect pipes and good to go.Im first to moan about stuff that doesn't fit but nothing wrong with these at all. ### ⭐⭐⭐⭐⭐ Would recommend *by on Reviewed in the United Kingdom 31 January 2026* Arrived on timeFits 110 injectors perfectly ### ⭐⭐⭐⭐ Next day delivery saved my bacon *by on Reviewed in the United Kingdom 3 July 2026* Worked perfectly ## Frequently Bought Together - 4 x Common Rail Diesel Injector Leak Off Pipe Return Connectors for 110 Injectors | 3 T's & 1L Connector | Durable Fuel System Connections | Automotive Parts - Autobar DL01 Diesel Leak Off Kit 1m Garage Workshop Replacement Spare Part, Black - 5pcs FOR BOSCH COMMON RAIL INJECTOR RETURN LEAK OFF PIPE CLIPS F00RJ00322 F00VC22003 --- ## 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.pt/products/419432653-4pcs-common-rail-diesel-injector-leak-off-pipe-return-connectors](https://www.desertcart.pt/products/419432653-4pcs-common-rail-diesel-injector-leak-off-pipe-return-connectors) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-06*
