injector lines or return line leaking?

[Crusty1]

Hi everyone, my first post and hoping someone has had this problem before, thanks in advance for your help!
I just had my injectors cleaned and tested, I refited them with new washers, put everything back together then started, idled bit rough with little miss but the big one was fuel was leaking around the top of injector lines?? I have replaced injector lines and still same,, could it be coming up from return line?? cheers

Need a bit more info mate. What motor and a pic maybe of the suspect line might help.

As above mate, more info will help.

I had a leak on my TD42 and I just needed to nip up the injector line to injector thread but I would also clean everything up and make sure you know exactly where It's leaking from too and advise.

cheers fellas , my mechanic tightened the shit out of my original lines and still leaked and burred the ends over so they were pretty well shot, got hold of another set from a gq fitted ok , still leaked, bought another set from gu and great fit,still leaked, mate put tiny camera against one and the footage looked like the fuel was coming up from return line? seems suspect but apparently can do it. the return line is old and has been braised up from my first injector service. i ordered another return line and should be here next week, i live 160 odd kms to nearest injector shop so hoping we can fix the problem, seems like a odd one ey? its a 99 gu td42t, had new turbo and intercooler fitted few months ago and dyno tuned by ufi and was running great.will post couple pics tomorrow

Your talking about the spill tube yeah? The one that runs from injector to injector? If so, thats the issue. Common as for these to leaking once you have taken it off.

It looks like the connection from injector line to injector weeps fuel around that thread, there's like a 3mm gap from injector line nut and return line nut , that's were the fuel come out.

Best to take a pic of exactly where you mean I reckon.
