You know how sometimes, if you stare at a problem long enough a simple solution will jump out at you? Well, I solved my heater hose delema and fixed a routing problem with my fuel system at the same time. Bad news is I need more parts now. A fuel log to run a single hose from my FPR to the carb, and fittings to run a hose to the nitrous selenoid. I was going to build a shield, but this seems to be working.
All I had to do was slightly relocate and angle my fuel pressure regulator (FPR) to allow one of the heater hose to take it's natural path to the waterpump. This also allowed me to no longer have one of the heater hoses in contact with the return line. As you can see, there's now at least 1" between any hose, structure or other hoses.
I drilled two holes big enough for a zip tie in the inner fender and used an old wire loom clamp as a spacer.
And routed the heater hose through the stock clamp on the fender.
