Is it stress cracking due to the way it is mounted?

It's mounted to the basement floor with 4 screws, that could be a possibility. It would be easy to relocate or maybe add something for reduced vibration

What about adding rubber mounting grommets?

When I added an accumulator tank I put sections of flexible hose like you'd use on a sink faucet between the pump and it's input and output lines. It reduces the vibration stress on the pump head compared to being attached to rigid lines as well as lessening the mechanical noise transmitted through the rigid plumbing.

The pumps feet are rubber, maybe add more.
I have the stainless steel lines too.
I might look for a rubber pad?

I've used Shurflo 2088 pumps for decades. I've had nothing but good luck with Shurflo 2088 pumps. Used them on my popup camper, class C, food cart, bus conversion and truck camper. Never had a housing crack. Worn them out and/or they start leaking. I tend to rebuild them. Since the 2088 has been reclassified as an "agricultural" pump, it's worth buying a new one than it is to buy the parts and take the time to rebuild the pump. I always keep an extra pump on hand. I've noticed pumps tend to go out at the worst possible time. I also have resold many a new or rebuilt pump to someone who had a pump die on them because they needed the pump right then. I always sell to have enough money to replace the pump (including shipping). I don't like to sell my extra pump off but if I'm in a good mood and the person hasn't been a jerk, I might sell it to them.
My current pump was bought in 2019. I was having a hard time finding the rebuild kits at a decent price so I just bought a new one ($65). Bought a new one exactly like it for my daughter's truck camper ($75). I have two rebuilt "extras" now. One stays in the truck, one stays in the bus.
Thinking of picking up a Seaflo marine pump next time. I haven't tried them but the reviews seem to be good and the price is better.

I was also looking at the Seaflo, it has a 4 year warranty too.

You need more room for the hoses to flex (vibrate), so as to reduce the stress on the cheap plastic pump head. Search the internet for RV pump noise reduction for various methods of vibration reduction. There are both videos and text/photo descriptions.
A variable speed model of pump would also generate less stress since it ramps speed up and down rather jerking to full on or off.

Add some rubber bushings for the foot mounts and the output line connection make it a flex hose (pimp - house main line).

Ordered the Seaflo pump. I'll go to the hardware store and look for isolation pads or bushings. Will install my spare pump in until I get all the parts together. Thanks for all the help
Thoughts on this
Mount pump to plywood with rubber bushings
Plywood to floor with additional rubber bushings that way the pump is not screwed directly to the floor

Perhaps overkill but here's what I did:
Covered one side of two pieces of plywood with dense foam (anti-fatigue mat material)
Sliced four, 1-inch thick "doughnuts" from a pool noodle
Glued the pool noodle pieces between the plywood panels
Screwed the water pump to the top of the plywood "sandwich"
Bungeed the pump and sandwich to the floor.
I also used flexible in/out hoses and an accumulator tank.
Now I have to listen to hear the water pump.
