4pcs Common Rail Diesel Injector Leak Off Pipe Return Connectors Fits Bosch 110 Injectors | 3 T's & 1L Connector | Durable Fuel System Connections | Automotive Parts

Fits absolutely fine on 1.9 cdti 120 engine. 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.

Unfortunately one of the set was broken on arrival. Not a problem as only need 2 from the set. However, these snapped on installation also. Very brittle plastic. I will now go to a main dealer and buy OE for improved quality.

Did the job nicely

Bought these to replace a broken return valve while serving the car. They arrived alright but the valves are ever so slightly the wrong size and shape. The rubber O ring does not seat well in the top of the injectors and caused them to leak diesel. The nozzle that goes into the connection pipes to the next return valve was too small for the hose. So I ended up going to a precision parts garage and getting original Bosch ones and binned these. Buy cheap and buy twice and that's what I got for buying these unfortunately.

Good product

Good

Not great quality compared to other Ive had before, but seem to work

Product didn’t fit the vehicle even though I checked multiple different ways that these would be compatible with my car, including adding my registration to amazons registration checker. Once fitted the part was loose, I thought I would try turning the engine over just incase the fitment wasn’t great but the leak had stopped, but nope diesel was still coming from the area where I had put the new valve. To make matters worse once I tried to remove the valve one of the plastic ends snapped off whilst removing.
