87 190E 2.3 Engine 102.985 Replacement pump does not match

I have purchased a replacement water pump and when in the process of installing I noticed the pump has what looks like an extra hose fitting in the 6 oclock position. The hose fitting size I.D. looks to be about 10mm. The original pump does not have this hose fitting.

I reviewed several parts sites concerning this year, model and engine and they all show pictures with this hose fitting in the 6 oclock position. I have pictures to show if necessary.

Do I have the correct water pump?

What is the fitting for?

I thank you in advance for your help.

84 300D acceleration concern

I test drove 1984 300D with 240K miles showing. She cranked and idled for approx 15 minutes. The dealer alerted me of sluggish acceleration. This was an under statement. I got her on the road and she barely made second gear, so I floored it, engine rev'd higher, pedal to the metal produced maxed speed of 45MPH. Easying off the gas seemed to help shift gear. I ran out of road, brought her back and same thing. asked dealer if he had any ideal what was causing the problem? He says... Fuel filter or maybe the turbo is going/gone bad. Question...
