FJ40 F engine..where the steel fuel line passes between the water pump thermostat housing and front of the valve cover...cool up to that point and very hot from that point to carb. Noticing a little vapor lock. What do you recommend for a 3-4" insulator to go around the fuel line to protect the line from the heat? I think asbestos is out of the question...and cant find any. Engine runs at 190 and never overheats. Pic below shows the line. Thanks, love this site.
