Another fuel question!

[michael bustamante]

Also when I tried to start the truck it wants to start but it stumbles and dies. So I pulled the fuel line off of the top of the engine and cranked it to make sure the fuel pump is pumping fuel. the fuel coming out was very Brown. I thought "great the fuel went bad." This is why I dropped my Wrangler tank so I could drain it clean it and put new gas but when I pulled the tank all the gas in it was clean. So why would I get brown gas coming out of the fuel to the engine? It is all new lines with a new filter and the engine did run for about 4 minutes before I turned it off and now it won't start. just stumbles
