My truck started leaking fuel while I was helping a friend move some trash to the dump. When I got out of the truck on the second trip I could see massive amounts of liquid on the ground and the smell in the air let me know that it was diesel fuel. When I popped the hood I could see fuel down in the reservoir/middle top of the engine. It was running down the back of the engine and down to the ground. I attempted to make it home without running out of fuel and managed to do so. I have parked it until I can get a chance to take a look at what the problem might be. I thought I would get a head start and post here to find out what the problem could be and the best way to correct it. I don't think that the fuel pump is bad in any way because it pumped fuel out all over the engine and on the ground while it was running and on the way home. I will start working on it this weekend and would appreciate any information that you think could help me correct the problem...thanks!
