2017 E400 Wagon Windshield washer pump leak
I assumed my leak was the pump grommet, however, it appears to be this part. I'm having difficulty finding the part number for this. It may be specific to the wagon because of it's rear wiper. It appears to be separate from the pump. The dealer has been no help. Does anyone have experience with this? Thanks!

Does that mean the pump and this part, as a unit? Or does that mean all the two tubes that come off either side of the white doohickey as well? If the white part and just the pump come together, great! Now my dealer just has to find the right part. The doohickey doesn’t seem to show. Do you have a wagon as well? Maybe it’s unique to the wagon (with the rear wiper). Thanks!

Thanks for your help on this. I put everything back together with a new grommet on the pump/reservoir, which I initially expected was leaking. There is no puddle this morning, perhaps I got lucky. I had seen a drip from that white part when I disassembled it.
I had the rear struts replaced way too early about 40,000 miles, no explanation, but they were clunking. My general tire wear seems unreasonable with cupping and replacement needed under 30,000 miles. Alignment doesn’t seem to help. I’ve seen this on my previous Benz wagons, still hard to accept. Thanks again.
