Fuel filter Mann or Bosch

Every single BMW I have ever owned has come to me with the factory date coded filter, every single one gets a new Mann in it and every time it runs better. Change your fuel filter ppl.

Possibly bad seals on the filter. Had one earlier this year that would do the same. Changed the filter for a Bosch model and the problem went away.

I replaced my fuel filter/regulator with a new one from Bosch, and the little rubber fuel injection hoses connected to it.

After I cycled ignition like 5 times to build fuel pressure it started to make this sound.

Struggled a bit after starting it but after 20 seconds settled and it now drives good.

Car feels solid no lack of power or nothing.

I dare to say it even drives better than before.

I do the air filter every second service (12k) and the fuel filter every 18k, or third service.

How old is that fuel filter? The "die on a hill" is a typical scenario for these old EFI Japanese cars when the filter is beyond saving.

Start by replacing the ancient NAPA fuel filter, and only use a Bosch version.

I replaced my V7 III fuel filter with a Mann MWK 44.

I had a Mann fuel filter from the previous owner so gave that to the shop. They called and said it was a fuel filter not an oil filter so they didn't need it.

the inlet side of the filter being completely gunked with black varnish.

So i went and replace the fuel filter to a Mann fuel filter but that did not solve the issue.
