<< One way to find out: Has anyone replaced their suction hose with the newly manufactured part from a legit DeLorean vendor AND still had the temperature related noise afterwards? >> I replaced the entire fuel injection system. This was a reliability and safety issue. If you don't know the condition of the main fuel hose from the filter to the distributor, replace it with the correct DMC part. Many cars still have the original hose. The heat and wear have caused many fuel hoses to split and catch on fire. The fuel pump kit and lower suction hose ($90.00 hose) have never given me any problems. (knock on wood). It seems that many of the problems, fuel, engine, etc., on the DML are new owners fixing poor workmanship and replacing incorrect non-DMC parts. It seems pretty simple with these cars, use correct DMC parts = reliable car. Mike Vin 3713
