[QUOTE="Fantabox, post: 429142, member: 19471"] [B]FINAL FOLLOWUP.....HOPEFULLY:[/B] After reading some feedback I was able to discern that the black substance was really old fuel. The old fuel had essentially congealed in the fuel lines and fuel rail, which was not checked prior to the first fuel pump swap. Thanks to everyone that offered their opinions and insights. I flushed the lines with some fresh fuel (again) along with some Seafoam, and was able to get a bunch more crud out of the fuel lines. It wasn't an incredible amount, but it took about 1.5 gallons worth of fuel and Seafoam to get it all out, or at least enough that I was not concerned. The rest was burned off once I had the Jeep running. The Jeep has been running for the last week, and driven a few miles without any issues. I will need to make some adjustments to the lifters, and get a new gasket...but that is about it for now. At some point I will be swapping in a Hemi motor (nothing crazy), but that is a long-term project. If anyone in Washington State, ideally Western Washington, has any leads on a low-mileage or new motor along with a transmission I am all eyes. Thank you all! P.S. YJ headlights rule them all!
