Plastic Fuel lines (Blue/yellow) routing

[pfrederi 18,333]

K-181s originally fed the fuel line behind the engine bearing plate and the block through the same area the stator output wires and coil power feed went.  I would imagine it get warm back there but back then it was heavy rubber  (neoprene) line.  Has anyone put the modern blue line or the yellow Tygon stuff  in there??  Thoughts???

I routed my B80 line down the bottom of the front cover like on a big block.  

Trina's 867 goes to the opposite side. In both cases I try to hold the line as still as possible.

No experience here Paul, but I see the yellow tygon fuel line is rated to 165F.     Should be OK.

I wont use the poly line in my shop, or on my own stuff.  Good for a couple years but if its going to be exposed to the sun any time...the stuff just falls apart.  I cringe when i think about the hundreds of feet of it ive sold..

What i was worried about is what happens when you first shut down and there is no cooling air flow would seem the temp would go up for a bit then settle.

Head temp easily reach 250°F as RED-Z06 showed the other day
