I have a Cub 2166 that is prone to vapor lock on very hot days.

On hot days, I run with the side panels removed and the tractor has the installed insulation around the fuel lines.

I was wondering if anyone knows of a better heat resistant fuel line that I might be able to install?

Hi W...

How are the air vanes and cooling passages on this tractor's engine? While the removed covers can let cooler air into the engine area it also can intoduce more dirt/grass/etc into the area s well.. This in case you haven't already checked/done this.. :goodl:

Aeroquip braided hose is heat resistant. It's also expensive.

any racing/performance/ and some rv shops have a wrap for fuel lines works great even on big blocks with headers

leaving the trim off the engine dont allow the fan to circulate are around the cooling fins and can cause it to run hotter too
