The Stovebolt Site Forums The Shop Area Engine Shop Heater hose retainer clip position?

At first glance that seems logical. However, I don't think that's what it's explicitly made for. The driver's side has the same scallop where no heater hose will ever be routed,

I think they are just scallops in the stamping to help keep the sheet metal rigid.

Also, the hoses aren't really out of the way down there. They'll be closer to the dizzy, draft tube, fuel pump and plug wires, etc.

The location of the clip on my truck puts the hoses up on top of the fender, truly out of the way of the passenger side of the engine.

Of course since the heater was added by the dealers, there probably is no standard "correct" location unless someone locates a Chevrolet accessory manual instructing dealers how and where to place the heater components.
