Well guys it finally happened. We finally got our first hot enough day in Memphis, Tennessee to require A/C and test out my new fuel rail/injector insulation. The install went okay, I put it on a while ago while it was still cold outside. The injector o-rings it came with are a perfect fit. The injector wraps are a so-so fit. The manifold shield I did not use since my factory shield (they're identical) is still intact. The fuel rail fits like a glove once you figure out where to cut the damn thing to make it POSSIBLE to wrap around the rail. Cut a hole for your schrader valve if equipped. But when it's all said and done? It looks great and fits tight. So it's gotta work, right?
UPDATE: July 7, 2019,
Everyone I have to admit I was wrong when I first wrote my review. I removed the unnecessary bickering and have to apologize to DEI, you guys did a good job after all. I don't know why I previously had symptoms of heat soaking on a ~70* day with this first installed but now that we are well into the 90's I haven't had ANY issues whatsoever. A/C on, hot humid days stuck in interstate traffic, stop and go, very little airflow through the radiator, yet when I get home and shut the Jeep off, change clothes, and head back out for the gym; no vapor lock.
I don't have any active fault codes and the only thing I've done to the engine since this install was I also replaced a faulty Throttle Position Sensor.
Perhaps the failing TPS gave me SIMILAR symptoms to vapor locking that were affected by excessive heat while still driving and I just thought this insulation kit was to blame.
I don't know, but I do know that I was wrong. I'm running harder and hotter than ever in Memphis traffic and getting absolutely NO vapor lock on any cylinder.
So this kit is doing great and I wouldn't hesitate to go wheeling in a desert somewhere. I'll continue to update this if anything changes but for now, I highly recommend this kit! I had to come back here to eat my words so I can keep my feedback as accurate as possible.
Plus, it's terribly simple to install. I'll add pictures soon.
Thanks again!
