Today I replaced the fuel pump, fuel filter lower mounting bracket and rubber mounts. I also removed, cleaned and painted the upper mounting bracket.
Which brings me to a question. After I installed it I ran the car and checked for leaks. It was leaking where I had replaced a piece of fuel line from the pump to the filter.
I used regular 5/16" fuel line and screw clamps. The original looked like it had a lining inside that had collapsed. (see pictures).
My question: Is it ok to use regular auto parts store fuel line, or does it have to be Mercedes-Benz?
I have changed out the screw clamps with the originals. I haven't tried it yet since it was freezing in the garage and I couldn't use my portable heater.
I have clamped the big line from the gas tank as a precaution until I can work on the car again.
