Fuel system has a leak and is spraying fuel all over engine. Wife noticed an odor in truck, smelled like fuel she stated. I have a Diesel 6.5 liter. Pulled Silverado over, popped hood, there was 1 puddle of leaked fuel with 2 smaller ones on the ground under engine. Cannot locate where leak is coming from. Went to back and noticed that entire back of truck is stained with splatters of fuel???? Drove another mile, pulled truck over, leak has stopped. Any suggestions? Is it safe to drive??
