Hey just wanted to say thanks for posting this video, it helped me diagnose the same issue I Had with my dodge. My tube o-rings were definitely leaking and now I no longer have the long crank. Thanks mang
My truck has been having starting issues for 3 years already, i have mastered the starting procedure with my issue, its crank it over half a rotation till the lift pump starts running, wait about 10 seconds or so then begin crancking, then it fires up quite quick untill you get around to fixing the problem. Thanks so much for your work. I will be ordering some pickup tubes soon to try.
Dude, thank you for all your videos, everyone else goes to the VP and lift pump which I've already done and still having hard start problems. I am definitely going to look into these!
Thanks I'm going to pull the tubes & replaced the O-rings as I've tried everything else, you have, up to this point, with the same issue. The O-ring issue seems to coincide, with the start / no start condition, pending where the pump to injector positioning. it t seems, these O-ring don't like the engine heat over time and begin to disintegrate. There are many different chemistry types, grades to durometer hardness of O-rings, referring to Nitrile, Buna, Viton etc... My next step is either get OEM injector tubes with the O-rings on them, or do a little more research, on fuel resistant high temperature types, As I'm an Industrial Mechanic, I've seen & had, O-ring compatibility issues before, in relationship, to different equipment and past scenario's . Thanks again.
One set of cross over tubes to be ordered shortly! Will be ordering through your links to help support the channel. Thank you so much for these videos. You're a baws!
Hey man I appreciate it! Hope it fixes your issues. I definitely don't have any sponsors or anything. So I just link for your guys convince, if you find them for a better price or a better brand by all means go with those 👍
I don’t comment on CZcams much but I have pretty much the same truck and have had all the same problems you have, I seriously appreciate every video you’ve made on this thing. It’s all right up my alley and super helpful! I say this with my old crossover tubes in my hand and a soon-to-not-leak cummins
Yeah, unfortunately it happens. I stopped using the head mount camera in later videos because of this. No way to check the angle while taking the video until it's done and in editing.
I replaced everything . Even the grommets on the t line , and I mean everything even cross over tube o rings I bought new cross over tubes that’s all I’m buying for this piece of shit if it doesn’t work then I’m throwing a check valve in it
So this fixed your long crank/cold start issue? I just recently upgraded my injectors as well as my vp44 but I reused my stock crossover tubes (166,000 miles), when I put it all back together it’s been having the long crank/cold start issue just like your truck was doing. If it sits for longer then an hour it cranks for 10-15 seconds to reprime the fuel system. I plan on changing my cross over tubes soon and if that doesn’t fix the hard start I’ll put my stock injectors back in to see if that makes it go back to the easy start. Thanks for any feedback
Mine was a visible leak at the head. I thought originally it was the fuel lines, so I replaced them and still couldn't get it to seal, once I replaced the crossover tubes I was able to get them to seal an no more leaks at the head. If it's an internal leak on the injector side I have no idea how'd youd be able to tell that.
To answer your first question, you can put a little oil around the o rings to ease installation. If you are installing new injectors, then you press the injector down first, then the cross over tube, and tighten both a little at the same time back and forth until they are to spec to ensure proper seating. If the injectors are not being replaced I did not find it necessary to touch them.
Great video series! I have a small fuel leak under the truck and it look like it's coming from the left side head. Do you know what size the O-Rings are? Thanks!
Not sure, but if and when you pull them take an old ring off or get an o ring multi size kit from harbor freight for a few bucks and just match the size.
@@AllThingsBoost Well I was hoping not to have to pull a Crossover tube, and be able to pre-order some O-Rings. So instead I pre-ordered the excellent Corssover tube extraction tool, AND I THANK YOU for showing how it works as a coaxial pulling tool in your video - Love your channel!

My tube o-rings were definitely leaking and now I no longer have the long crank.
Thanks mang
Adding a little bit of oil/assembly lube onto the orings helps the crossover tubes seat better to. Just so you for future reference
And as far as aftermarket fuel lines pro source diesel makes a much better set as well.

Thanks for showing this. I feel more comfortable doing this now that I have seen it done.

Appreciate it and good luck to you sir
You should loosen the injectors themselves also and alternate tightening the crossover and injector. This way they seal as you tighten them.
About to injectors on my 2002. Thanks for the info I know it’s not injectors your doing but the VP44 lines are my biggest fear😂
Once you do it you'll realize ita not that bad, probably had that sucker out 3 or 4 times now chasing fuel and oil leaks
You are constantly holding the parts below the line of sight of the camera, so we cannot see what you are talking about.
Yeah, unfortunately it happens. I stopped using the head mount camera in later videos because of this. No way to check the angle while taking the video until it's done and in editing.
Just put a little oil ring n they will snap in easy
Great repair!!
I replaced everything . Even the grommets on the t line , and I mean everything even cross over tube o rings I bought new cross over tubes that’s all I’m buying for this piece of shit if it doesn’t work then I’m throwing a check valve in it
Shouldn't you dip them in fresh engine oil first?
Ok so did this fix the slow start issue because my 1998 is cranking and cranking before it starts.
Yes it did
Where did you get that tool?
What socket is that for torquing?
Did you leave the check valve down by the pump?
Yes. Never bothered to remove it, but its not needed anymore
did you ever get any white smoke after it fired up when you were still having the cold start issues?
Yeah, excess cranking would shove some extra fuel in, so I'd get some white on startup from time to time.
how have these held up? I want new ones but its hard to find oe ones and ive read some conflicting information on aftermarket tubes.
They've been good, no issues from them.
So this fixed your long crank/cold start issue?

Yep, 100% fixed my long cranks. They should be replaced with injectors at the same time to prevent the exact issue you're having of a bad seal.
How did you determine the cross over tubes were leaking?
Could you see it weeping externally or is it and internal leak ?
How do you test it?
Mine was a visible leak at the head. I thought originally it was the fuel lines, so I replaced them and still couldn't get it to seal, once I replaced the crossover tubes I was able to get them to seal an no more leaks at the head. If it's an internal leak on the injector side I have no idea how'd youd be able to tell that.
Did you have a long crank time?
Yes, that was a symptom
I'm more concerned about new tubes not seating to the old injectors
To answer your first question, you can put a little oil around the o rings to ease installation.
If you are installing new injectors, then you press the injector down first, then the cross over tube, and tighten both a little at the same time back and forth until they are to spec to ensure proper seating. If the injectors are not being replaced I did not find it necessary to touch them.
@@AllThingsBoost thanks, about to do this. My lines are leaking. Bought new tubes and another set of used lines. I hope it works
Great video series!
I have a small fuel leak under the truck and it look like it's coming from the left side head.
Do you know what size the O-Rings are? Thanks!
