Hi Guys. Need help with inline fuel pump supply hose removal. Realoem and another picture from the forum show a regular clamp but don't see the clamp in my car. Any idea how to remove the hose in this setup. The hose is rubbing against the bracket realoem #23 showing a protective hose which I don't see either. What is the best way to replace the hose tape new hose to old and pull from the transfer pump end? Thanks in advance for all help.

Looks like a cover for the pump. Should come off with some parts removal revealing the hose clamp.

It's there, just under the soundproofing cover. Might even be original like the return hose in your picture and you may have to cut the clamp off. But it's there, just hiding.

It is hiding there alright still has an oetiker clamp may well be the original pump car has 200k amazing. Also need to replace the big 12x18 hose to the tank. Does one need to drop the tank to do that or simply snake it through. THANK YOU ALL for the great advice.

You can just loosen the tank bolts and give yourself an extra 1/2 inch to work with. That's all I did when I replaced the fuel line. Of course you could drop it more than that if you have the right tools and such, but that seems to be more work than necessary.

At 200K I'd expect it to be original, along with the fuel lines which should have been replaced long ago. 535 pumps don't seem to last quite as long as the ones in 528e's, the higher fuel pressure I'd guess, but still I'd say are typically good for ~250K. Of course the in tank pump goes at 100k, but that's different.

Replacing the suction hose? Just lower the tank as noted above, no need to remove it. Still, better if it's near empty, but not essential. It is essential however not to be full, the top of the sending unit and the suction hose are below the top of the tank and will try to drain the top inch or so of fuel if attempted with a full tank.
