Dont waste your time or money. That part will break.
I bought this hose as a temporary fix until I could get a hold of a genuine part. I fitted this in hopes it would keep my Caddy on the road for a couple of days. Initially when fitted it fixed my problems and all seemed well. I took the van for a quick 2 mile test run and warm up around my town and within this 5 minute period the seals perished and hose came apart causing a huge fuel leak. This part is terrible quality, lacks any real durability and WILL cause you problems. Do not waste your money and time, get an OEM or Bosch part.

Works but not for long
Work as a temp fix but quickly failed. Continued fuel leakage after a few hundred miles

Poor quality
The pipe looked good but when I tried to fit it the pipe on number 4 was shorter than the original so was a tight fit. After a day or two it started to leak so I had to get a genuine one at £120 a ridiculous price but it fit and is still working. There’s a moral to this tale.
