I've got a pretty serious fuel leak right at the pump.

Not sure if it's a broken line or fitting or what??

It's a steady drip at the fitting that is right against the block of course.

Not sure which injector it goes to.

Truck has been slightly difficult to start with lots of smoke at startup, I'm thinking this loose fitting and/or broken line has been allowing it to suck air and cause the hard startup??


Anyone know how to check or tighten this fitting without undoing all the other lines to get at this back one??

 

$45 Mac 3/4 offset wrench is what I use.

 

Yeah I got it off...... Doesn't look bad to me but still leaked even after I tightened it a little. Ordered a new one from Cummins $135
