Replaced my injectors. Now #2 is leaking. Cross over tube is in. Heard it "pop" into place. Hand threaded all the lines back on.... Can't figure out why... Any and all help is welcome!

what year truck. did you change o-rings on cross over tube? where is leak, inside or out? need more info.

2002. Outside. Onto the block Didn't change the orings on cross over tube. 2nd time I've done injectors. Weren't leaking last time.

If it is pumping fuel out to where it is running off the engine you have a leak, if it is just damp with fuel it is just fuel that was trapped in the void in the head between the line nut and crossover tube and will weep out and dry after a few days of being warmed up good. Very common and nothing to worry about happens all the time and folks think they have a leak which they do not.

No. It runs. There's a puddle after I drive.

I'm trying to figure out what is causing the leak

Change the o-ring

I've never done it but there was something about the tightening order posted. someone will come along. I think it was tightening the cross overs before the injector body. I'm saying yes to the Oring.

Also agree it very well could be a o-ring.

When I installed mine I tightened the injectors and then installed the cross over tubes and had more than one leak. I went back and reversed the order. Installed the injectors then then crossover tubes, tightened the fuel lines and then tightened the injectors and all my leaks went away. That said I think I would put on new o ring on and see if that stops it.

O ring on the crossover tube?

Yes. That is the o-ring. Is it only one or more?

Okay. I have a full set of extra tubes. I'll try it out

CHanges the cross over tube. Didn't fix it.

Changed the line and BAM no more leaks.

:thumb1:Glad you got it, the lines can get hairline cracks or over tightened and distorted.

Over tightened luckily my buddy just did a pPump swap. So had a full set of lines for $50!

Good to hear.

I know have a extra set of lines if anyone needs any other then #2...

I need one of the blue hold down blocks. Did you by any chance get them with the lines?

What's it look like. Lol I have them all.
