## Questions & Answers

**Q: Why does it say this doesn’t work on 02 wrangler 4.0?**
A: Not sure, but I can tell you it works on a 99 Grand Cherokee 4.0 and an 03 Grand Cherokee 4.0. Not sure what the differences between the wrangler and Grand Cherokee 4.0’s are

**Q: Does it fit a 2003 TJ wrangler ?**
A: This Jeep Fuel Rail kit is meant for any Jeep with a 4.0L inline 6 cylinder engine, '97 - '04. This will also work for mater model 4.0L inline 6cyl engine with some modification to the fuel rail sleeve.

**Q: Is there any reason why this shield/kit would not fit a 1996 Cherokee XJ 4.0?**
A: If the intakes and fuel rail look the same, it'll likely fit.. There have been small changes in the intake manifold over the years that could make the flat shield not fit..

**Q: Will this fit an 82 cj7 4.2 that has mopar mpi installed? it is based on the wrangler 4.0 mpi set up.**
A: Can’t speak specifically to that motor, but this set fits the 99-03 4.0 in the Grand Cherokee for sure and I’m sure the same years of Wrangler.

I use my Jeep XJ to tow a small boat, so I am all too familiar with heat soak issues. I would leave it running on the boat ramp so I didn't have to shudder and shake, barely making it up the ramp. So far this kit solved the problem. I also added hood vents to keep the engine bay Temps down, but I'm sure this kit is enough to stop the heat soak problems. All the fuel rail brackets and holes lined up perfectly, except for the pressure regulator, but one cut with some scissors fixed that. My factory heat shield was totally destroyed, see photo, so the new one looks great. Top of the engine looks much better. I found it best to install the injector wraps after the fuel rail was re-installed. It was too difficult to line up the injectors with holes and connect the electrical connectors with the wraps installed. Overall a nice product. I will definitely save some fuel/wear and tear by not leaving the jeep running during stops.
