I am servicing my new 1987 300 SDL for the first time.

When I first purchased it I took it to my regular MB mechanic to give it a once over and change all fluids and filters.

The fuel pre-filter looks clogged so I was getting ready to change it. The arrow on the pre-filter is pointing AWAY from the IP. Shouldn't it be pointing towards the IP since that is where the flow is going.

It's the straight inline filter type.
