How do I get these out?

So long story short, generator crapped out, while I'm in there I'm replacing everything I can, gaskets, fuel lines, fuel pumps, glow plugs, etc.

Looking for advice to get the fuel injector things out so I don't damage them or lose them. Want to replace all 20 o-rings. Looking to finally wrap up my 3 month project... 2 months waiting for parts!

Hey
The tubes just pull out but before you do ensure you clean around the area so crap doesn't fall into the holes.


I pressure tested the rails and the heads after reassembly to ensure no leaks cause it would be a headache to repair after.

I actually haven't attempted to pull them out yet, it was a bitch to get the rail out and all 2 of them stayed in the head so I don't expect them to pull out easily. Any tricks other than grabbing them with a set of pliers? Also how'd you pressure test? Would be a head to have to pull it all apart again. Did you just rig something up and attach an air pressure gauge to the end of the rail?

It was pretty straight forward mind you I had to make a small threaded block on my lathe.


Once I connected all things shown in the pictures I pumped/bled fuel thru the rail till no air was left then tightened the banjo bolt and raised pressure to 15psi and left it and continued to check for leaks.


Hope that helps

Drag

Drag,
I believe I see what you did here. Attached your pump to return line from the rail and blocked the banjo. Just want to confirm that's what I'm looking at. Wish I bought a pump with a a gauge now! Oh well another tool for the pot. Thanks!

Yep that's it, just blocked off one line and pumped diesel in the other.

Drag, I pmed you asking about the injector harness. If you didn't get it, to summarize the male connector to the injector harness started spinning. Having trouble getting the female connector out to check it. Any info you can give on this? Whether or not you think it'll be a problem or not.

My engine is still in so it's fairly difficult to work with
