accidentally put deisel in the tank.. is this easily repaired?

It is for a shop with equipment. Remove the fuel tank, drain, clean, repeat. Change the engine oil a few times. Clean as much of the diesel out as you can.

Hello, the tank must be emptied and fuel lines will need to be flushed. The procedure should be performed by a professional technician. Approximate cost would start at $300.00 depending on the extent of fuel contamination (how long engine ran before discovering issue). Please give me a call if you would like to discuss it further, 714-484-1982 ask for Jerry. Thank you.
