Hi all. I purchased a hose kit upper,lower and heater hoses. The kit didnt come with the heater hose from the water pump to the firewall. I removed a well worn part number 18077L molded hose from that spot. I cant seem to find a molded hose to replace it that isnt discontinued. Will standard heater hose work? its a really tight bend to clear the tensioner/alternator bracket.... Thanks for any input.
