Well discussed in many threads - but here is one - https://sprinter-source.com/forum/showthread.php?t=48673&highlight=turbo+inlet+seal

Changed my fuel filter out, just did an inspection on the turbo fitting, looked fine, even though I purchased a new one just in case. Made sure the clamp was secured properly and stayed with the existing one. Put 15K on it now, with no issue. Will review it on the next fuelmfilter swap out.
