Sorry you are having issues. I have Dennis pumps in my 39 coupe and in my 52 F1.

Truck 2 years
Car 5 years

No issues.

However I should mention. Since the truck needed so much work, the pumps sat on my shelf for over 6 months. When I was ready to install I noticed one of the fins had a crack. I called and while long after purchase they replaced the pump free of charge. I can’t recall if I paid for postage to return damaged pump.
