Fuel line routing through front fender well

OK, to be clear - from the rear to the front is already hard line with gravel guard. From the tank it runs along the inside of the wheel arch and up the frame connector to the trans cross member. That part is done. I am only concerned with the area next to the transmission bellhousing and how to get the fuel line around it and back into the engine bay forward of the firewall.

Previously, the fuel line did run along the inner frame into the engine bay like the factory routing. At that point, the car went 12.0 @ 110. After 8 years of re-doing the car, it should be somewhat faster requiring stricter adherence to safety. Hence the change in routing.

So, the face of the bell is about 22" forward of the cross member. Right before the trans cross member, I can run the line to the outside of the frame connector and through the outboard bulkheads. The question is this; whether that short piece of flex hose in the front wheel well will be OK on the street (I'm thinking most likely it will be) or, do I run the line through the space between the firewall and frame rail where I'd still probably need to put some sort of big, heavy protective shield around it to protect it from a potential trans explosion.
