Damn, Fuel system stuff in the library says nothing about the temp sensor.
Wouldn't be hard to do the radiator type cooler along the framerail if it does get hot.
only thing i've found Dustin is that fuel cooler is designed to keep the fuel at or below 158* at the inlet to hpfp . Couldnt find anything on a sensor
How come no one does it that way, or at least I haven't seen it? All my piping were Jet Hot ceramic coated, never was told about doing only the insides and not the outer.
Jet-Hot points out that realizing the full anti-corrosion benefits of header coatings requires coating the headers on their inside as well as outside surfaces. Not all competitors coat the inside surfaces, which isn’t good because exhaust gases themselves contain corrosive compounds. If the inside isn’t coated, the header eventually rusts through from the inside out. Coating only the outside can also cause another problem: Mild steel tubing fatigues when it gets too hot. An outer-only thermal barrier blocks the heat from radiating through the exterior metal surface, while the lack of an inner barrier exposes the metal to added “trapped” heat. In a scenario reminiscent of that caused by the dreaded “curse of the mummified headers” (outer cloth wraps used by some racers), the result can be literal disintegration of the mild-steel tubing.

Second reason you don't see internal coatings more often.... most people don't use ceramic coatings for their "ceramic" coatings, lol. Most of them in the 0.002" thickness are really just a high temp paint for the most part. If this is used on the inside it will flake off and be gone in no time. Then they will be faced with redoing someones parts again and again, as well as possibly lose business over it.... so.... they say F it and just don't do it.
Found some similar sentiment from a leader in the industry.... Jet Hot...
Spot on.
I built a tiny little header for an ATV I made one time that was a 630cc two cylinder powered side-by-side. I ran the header for at least a year or so without any issue whatsoever. At night it would glow bright red as the little engine tore through mud holes and muddy pastures, yet it never showed even the slightest signs of fatigue, as I said, for a year or more. When my wife rode with me she complained about the heat on longer rides, so the day before a ride one weekend I wrapped the entire system with good, quality wrap. Did an excellent job and it was nice and cleanly done.
Roughly 2 hours into the ride, on a header that had shown perfect resilience for hundreds of rides previously..... the header had overheated to such an extent that it mechanically failed. The wrap was literally the only thing still holding it together... It cracked in multiple places and broke clean in two at another.
A header that was perfectly fine for tons of rides was 100% destroyed in a matter of hours after the wrap started trapping the heat in, overheating the part.
It's not rocket science. Take one guy and put him in 100 degree heat with shorts and a T-shirt on and then take another wearing a black Fur coat and ski-bibs.
Work each of them hard. Which one has a stroke first, lol.
