Long Fuel Pump Removal Question
« on: September 29, 2015, 05:54:11 »
I have the 230sl down for a few weeks for other work. So, I figured I'd drain the fuel tank (looks great, strainer clean) and replace the fuel filter.

I would also like to check the inlet filter on the fuel pump (long style). The canister around the pump is making it a bear. It has only two holes...one for the inlet hose, one for the outlet. Even loosening the canister mounting screws, I can't get the canister to move side to side enough to even access the hose clamps attaching the hoses to the pump. I need to get those hose off so I cab drop the protective canister or at least get to the inlet.

Somebody, please tell me the miracle secret! Thanks

Well, one suggestion would be to go with the Alexander the Great approach - just cut the fuel hoses off! If the hoses are old and dry, you are wise to replace them anyway

Fuel hoses are perfect...like new. Guy before had them done. But I want to be sure that strainer is clean. I don't want to cut the hoses

I think you just have to take everything apart.  Remove the fuel lines then the cover, then the pump.  Some of the work required to service these cars is NOT a shining example of German engineering.

If the tank strainer is clean and you aren't having any fuel starvation, no need to check the pump filter.

WRONG....the tank strainer was 100% perfectly  clean. The fuel pump strainer was 75% gummed up with "gas jello". Don't think just  because  one  is clean  the other is too. I was told that by a local guy who has been working on these for 30years...and he was right. Good thing I checked.

Figured out easily how to remove the hoses....remove the outlet hose fitting with a 19mm. Put a screwdriver through the same housing cover hole so you can get the screwdriver on the hose clamp and remove the hose clamp from the inlet. Was a piece of cake....just had to think about it for a minute or two.
