Hello my name is XXXXX XXXXX I will be mor than happy to asisst you.

 

Does the fuel pump work on the vehicle?

Customer: replied 4 years ago.
I accidentally put E85 in this vehicle, and I want to get it out. Yes, the fuel pump works.
Expert:  Matt J replied 4 years ago.

The best way is to unhook the fuel like on the drivers side on the inside of the frame rail. Then take a hose, connect it to the fuel line, and put it into a container. Now go to the fuse block under the hood and remove the fuel pump relay. See picture below. You will need to take a piece of wire and jump Slot 87 to Slot 30. Looking at the picture below it will match up if you are standing on the drivers side of the vehicle looking down at the fuse block.

 

Once you jump these to slots then the fuel pump will kick on and push the fuel out to the container.

The only other ways are to remove the tank and dump it or buy a gas siphon

 

If you have any questions please let me know.
