diesel Fuel in gas engine

[jare Tara]

Do you have a return system or a dead head fuel system in your tahoe?

Diesel won't plug anything in a gas system, it just won't run very well or at all if you get to much of it.

Your repair is going to be to pump the tank dry, if you have a return system from the fuel rail you can connect that port to a hose and jump your fuel pump relay to start filling gas cans.

If you don't have a return system I would rig a hose off of the fuel pressure port to a gas can and then jump the fuel pump relay.

You shouldn't need to dismantle anything, just pump it dry using the tahoe's fuel pump while it's sitting on level ground and it will be clean enough to run again; using the port on the fuel rail to drain the system insures you get the rails pretty clean as well.

Your not the first one to deal with this, it makes you feel silly but you didn't damage any hard parts.

Just getting back, that’s sounds great. I’ll put it out after the electric fuel pump! When the fuel pump stops pumping fuel, don’t the fuel rails have the diesel sitting there still? Thank you!!!!

When it stops pumping just dump another gallon of clean gas in the tank and pump that out to flush the lines
