That's not a valid comparison when the pump is on your car its working harder at pressure and will build up heat more than a pump running at pretty much a near 0 pressure.
The pump in the jar may actually be working harder depending on how much of a restriction the line and small volume of fuel is putting on it, and definitely for a much longer amount of time. It has been operating continuously at atmospheric pressure, while in the car it only runs for 20 minutes at a time at low pressure every 9 to 10 hours on average.
And, even though it's at only 12v vs. the 15v of the boost-a-pump, it's probably running hotter due to there being so little fuel to absorb and dissipate the heat, compared to a 13 gallon tank with air blowing over it at highway speeds.
Gasoline does eat the rubber as seen and you're running it through the hose.
It appears to affect only the outside of just the Goodyear hose...which I'm not running on my car.
