I purchased some heater hose which is 19.05mm I/D, which fits over the oil hose. I will use this hose to protect the oil hose from possible rubbing areas. I have been thinking of how to secure the oil hose as it passes the alternator. TAF use cable ties, however , a P-Clip would be much better. I made a bracket and riveted it to the alternator support arm and then used a P-Clip to secure the hose. I stiil need to install some heat sleeve on the oil hose in the area above the exhaust pipe.
