4 x Common Rail Diesel Injector Leak Off Pipe Return Connectors Bosch 110 | 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.

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.

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.

I had to fettle the parts with a small file as the mouldings had burr on them, I also had to replace the seals as they were not up to standards, got me out of a pickle but I had to improvise

Good

All faulty like this and leaked fuel straight away

Found them to be quite brittle, broke two trying to click them into injector head.
