I had a leak at the molded fitting of the heater inlet hose. I ordered a replacement hose part # 42348374. The new hose came in and it appears different in that the new hose has a white molded fitting versus the black original, and the original hose had what appears to be a molded-in seal and I believe the new hose had an o-ring. I installed the new hose and had a steady drip, drip drip and the connector does not feel like it is a tight fit. Has anyone had this problem, or know of a solution. I plan on checking when I get home to see if the o-ring has gotten rolled or pinched. Maybe I should have lubricated it before installation but again it did not appear to give a good tight fit when installed.
