Hey guys,
Local MB parts dept tells me my good old 420 has a fuel strainer just like the diesels. So maybe time to remove clean and replace...wish I had a lift!
Where is the thing, what tools do I need to remove it?
Thanks

Are you having a fuel starvation issue?

Doesn't require cleaning unless you are having problems!

Yes that is why I ask. Already checked pumps, changed filter, etc. Has to be strainer. Somewhere on the fotum someone said that replacing same would destroy the strainer and tubing going to it? Others say you can clean with carb cleaner and replace ? What is alternative to a socket for that big 42mm nut?
Should be simple job but sounds like a pain in the A.

What makes you absolutely sure that it's the tank strainer? There is a small strainer at the fuel distributor inlet too.

Well..I did not know about the "small strainer" at the fuel distributor but I believe the problem is in the tank as the fuel is shutting off when going around corners and just happened when my fuel level was abnormally low. Filling tank helps and greatly reduces the problem.

Have you performed a fuel delivery test?

Should deliver a liter in 25 seconds at the return line.

If the problem happens only while low on fuel & turning, most likely there is a problem in the tank related to the "slosh" pot. That is made into the tank.

Yes. isn't the "slosh" pot where the fuel strainer is located? Don't you think that sloshing fuel sediment is closing and opening that strainer? So my questions about location an removal process and tools?

What do you need a lift for? Isn't your tank behind your backseat? I had my tank out in about 3 hours with just the mercedes jack, jackstands and some tools - no specialty tools either.

Just unhook the lines that protrude from the bottom of the car, unbolt it inside the trunk, disconnect the fuel sender, remove the cap & fuel neck grommet and wiggle it out.

And yes, they can get very clogged, especially if the vehicle has sat for a while or you've been using low quality gas. Or someone has poured something in your tank. When I got my car (which sat for 2 years and was of course 24 years old), it passed fuel at about 1oz/minute. Even direct spraying of brake cleaner on it had very little effect on cleaning it.
