Just an update — custom heat shield and DEI fuel rail and injector wrap have been installed
I’m happy to report that this has seemed to cure my heat soak issues while running — no more dying while sitting in traffic
Before the heat shields this XJ couldn’t be left running while stopped for more than a few minutes once warmed up in 70* weather — the fuel would vaporize in the fuel rail/injectors
During this past 95* heatwave I purposely left the engine running while stopped multiple times — no issues, just keeps running
I did also install an E fan manual override switch just in case — haven't needed to use it while the engine is running
