For safety reasons it would not be advisable to use rubber line anywhere near the manifold and exhaust pipe.
if it was acceptable the manufacturer would have done it from the factory.
Exactly!

Very true. To help illustrate the danger, I created the following image which clearly shows the close proximity of the fuel line to the manifold on my Massey Ferguson 135 tractor. Not to mention the fact that there is ten gallons of gasoline perched directly above the manifold. Many other tractors are very similar in design.
Previously, it was mentioned that using fuel injection rubber hose would mitigate the risk of heat-related failure... For those who believe that using rubber hose for fuel lines on vintage tractors is a good idea, here are some facts to consider.
Most fuel injection rubber hose is manufactured to SAE J30R9 specifications, having a temperature range of -34 to 135 C (-29 to 275 F), with intermittent use at 150 C (302 F). As previously mentioned, the fuel lines on most vintage tractors are routed very close to the intake/exhaust manifold, and exhaust manifold temperatures range between 500 to 1000 F or more, far exceeding the maximum temperature range of the rubber hose.

i guess you could use soft lines designed for brakes.. at a considerable expense..
I've never tested plain epdm rubber hose and brake juice.. might dissolve it. I know neither will take the pressure unless the braided hose for high pressure pumps.
I just stick to metal anywhere i can on most things.
