I just received my 5/8" black hose that I ordered and notice that the walls are not as thick as the 3/4" clear hose that I have. Is the thinner walled hose more prone to leakage and failure?
Ditto what len said. Most of the problem happened when the hose was not attached properly. You really need a hose clamp or a zip tie to make sure it does not come loose due to the vibration, etc..
