Hey guys! I'm new here, just signed up today. Was gonna make an intro post but my work truck/ DD is leaking diesel like it's goin outta style. So here's the story, have replaced injectors due to them being old. Got new return lines, o-rings, the whole package. Notice diesel pooling under the engine (months after replacing everything) started her up and looked for where it was coming from. Turns out the rings on an injector got chewed up. Fixed that today. And went driving. Noticed a lot of hesitation under throttle and an even stronger diesel smell than before. So cranked her over and checked everything. No return lines or anything leaking. Long story short, on of the actual fuel lines at the pump is squirting everywhere. Diesel is covering my engine bay. My question is, how do I fix it? I tried tightening it a little but it was pretty tight. And hard to get to, it's the line that goes to #4. Thanks guys!

 

welcome to FTE.
it sounds like the line for #4 is bad and going to need replacing.
