Trying something I've never used before. I've had higher fuel temps than I'd like, not enough to cause any issues, just gonna see if I can make it better. As always, as the weather warms up, we've already had some recent vapor lock threads from the carb guys. Throwing this out there as awareness, as well as to see if any of you have used something similar and your results.
They make this stuff in numerous sizes, from 1/2" to 5 or 6 inches for wrapping charge pipes. It uses Velcro sewn into the wrap to attach to itself.(I did use tie wraps on the ends where it was stretched pretty tight to cover the fittings) Mine is 1 1/2", and is wrapped on top of common 1/2" pipe insulation. I can monitor actual fuel temps, so I should be able to tell if it helps or not. I did the feed and return crossovers from the rails that are close to the intake, and especially the water crossover in front, and the return line that runs in the path of the air from the cooling fans. Also did the filter which is fairly close to the valve cover(thermal sleeve only, as this is close to 1 1/2" already)
Will report my findings, would love to hear yours
