Pressurized it to 30 PSI and it dropped 1.75 PSI in a minute. Pretty disappointing after spending nearly 1,600 to try to avoid poor quality problems. Unfortunately it was already installed in the truck and I didn't have time pull it out and exchange it for another. Will a leak of that amount have any effect on fuel mileage??

the rule of thumb is 10 psi in one minute. Yours is fine!. they do not have to be a perfect seal.
