My new to me 93 is not airing up. I just replaced the pump because that is what the shop diagnosed the problem as. The pump runs now but the car does not air up. I get close to it and i can hear a leak. It was hard to tell if it was coming from the strut or the compressor with the tires on. So i started wiggling the air lines where they plug in and then it made the air leak louder. So i suspect that the air line is not sealing or in all of the way. if i cut the air lines with a razor blade will it be good enough or is there a better way to fix the lines?
