What is this pipe sealant?

We have a 2004 MADP and I removed the pegboard in the basement bay today to access the fresh water tank so I could install an anti-siphon valve in the water overflow hose. Newmar used some sort of sealant around where the drain and vent pipes enter the top of the gray and black tanks. The sealant is like kid's modeling clay. What is it? Normal plumber's putty one would use to install a drain in a sink?

Since it is 15 years old on our coach, I thought about resealing the drain pipes as long as I am in there. Has anyone done this? What did you use?

Also, besides the drain and vent ABS pipes going into the tops of the gray (second picture) and black (first picture) tanks, there is also what looks like a 1 1/4" flexible hose plumbed into the top of of each tank. What is their purpose. One is visible in the second picture below.

If I just pull off the existing sealant, will that product adhere to the same surfaces or do I need additional prep?

Looks like butyl tape molded around the pipe:

If it isn't leaking or hasn't leaked I'd leave it alone.

Good advice! On mine the sealant had cracked so I didn't remove the existing sealant but just filling in the crack and built another layer around the pipe. I used plumbers putty. Has held just fine. Yours don't appear to be cracked so I would leave it alone.
