So lately Ive been noticing a small puddle of diesel under my 240 when it has been parked for an extended period of time. I haven't worked recently and am noticing that puddle getting bigger every day. Where could it be leaking diesel fuel??? Near the injecter pump or is it a cracked fuel line or what? Also, I do know that the engine in the vehicle is not original and that it was recently replaced so could this be the problem any help would be absolutely fantastic. Thanks!
