Seems to be fitting tightly

My washer pump was leaking and I assumed it was the rubber bellows. After I received by parts, I removed the foot pump assembly and started pulling it apart. My leak was actually a loose fitting on the back side and stripped threads on it. The rubber bellows was actually fine but I decided it was apart, replace it with the new one. I got it all apart and was working the spring and internal threaded disc fitting inside and saw that the bellows was ripped. I was being careful too so it either came in ripped or it took almost no effort to rip. Its useless junk. I slipped the components back into the 50 year old bellows and had no trouble and no damage. Also, I would throw out there that the look was good, but the rubber feel like a repro part with rough texture that made me fee like it might deteriorate quickly.
