Default SLK 230 Fuel Pump - do it yourself?


i have a 2001 SLK 230 75k.

there is a whining noise from the back which i guessed was the fuel pump. i ignored it for 10k miles until i started having acceleration problems starting from zero. but when already driving above 5-10 mph there is no problem with the acceleration. i can do 90mph on the highway and there will be no issues. but as soon as i stop at a red light it will take the engine 5-6 full seconds to move the car (!). but it happens random maybe every other day.

anyways - i bought a fuel pump since it looks like a simple part BUT i cant find anywhere a do it yourself manual.

does anyone know where to get a manual ? heynes dont make them for the SLK.
or if anyone know how to do that in a few step would be great help.

thank you

(offcourse it could be something else, like spark plugs? or else? i am not sure, not expert or close to it. just handy with tools and dont want to pay $1200 to replace the fuel pump, or $250 for full car diagnostics)

this video was made 10k miles ago...

Regarding a do-it yourself manual, heres a manual for the crossfire its the same as an slk just a different body style
