I am trying to install a Flex-A-Lite PS cooler (same as trans/engine cooler) and the hose that was provided is not long enough. so i went to 4 auto parts stores to find a hose. they have the correct I.D. hose but the auto parts hose is not as thick. can i get away with using the thinner stuff or do i have to find the thicker hose somewhere? and if so where?
