2011 W212 Fuel Pump Cover Replacement ring 10mm studs

If the metal glue can reach the strength as brochure as 5020 psi, that's strong away than 5nm. And I don't think any metal shop would dare to weld a fuel tank for you unless you remove the tank from the car and completely clean off the gasoline.

@Senior Leigh | 老李 Thank you for your response. I also think that the cold weld with epoxy glue looks like a good alternative, as long as the strength can be achieved. Now I realize the cover ring does not need to be so tight, as there is no pressure build up from the fuel, it only serves as a seal. You're right about welding a new bolt to the tank, unless it is removed and cleaned, at that point I'd be better off buying a new tank assembly.

I think Senior Leigh is right, welding a new bolt in this tank is rather difficult. I am going to try the cold weld. The specs for the J-B Weld exceed the 5 Nm required from the bolt. Fortunately, fuel pressure comes from the fuel pump, the tank itself has no pressure, other than the gasoline vapor.

Oh, that's sucks!

The bolts are the bolts and tank are inseparable, before replacing the tank, I suggest you try the epoxy metal glue. I can find the high strength (5020 psi) is J-B weld 8265S Or you might research something stronger glue else.
