Why create two threads on the same topic? - now merged.
The videos don't work.
Who's doing the install of these fuel pumps - might want to hire a competent mechanic.

I recommend a 1/2" drive for this application.
4mm, 5mm, 6mm, 7mm, 8mm, 10mm

Not sure why the dealership didn't retrieve any codes.
How difficult would this be for me to check if I need this or not?
The PDF @Haz attached shows it under one hour labor for the repair.
