6.4 Banjo bolts?

[Reezy71x]

building my truck up, and during that I keep hearing about banjo bolts? Does anybody want to explain to me what they are? Thanks, for I am still learning about the 6.0 and diesels in general so bare with me!

they are the bolts that hold the banjo fittings on the front of the heads. Follow the tubing off the regulator and you will see them terminate on the front of the heads.

the only difference is the 6.4's don't have a check valve whereas the 6.0's do. Pretty easy and cheap job to do, supposedly aids in fuel delivery, never had a straight answer. While your there get the blue spring for the fuel pressure regulator, that is proven to be needed.

Save it for a monitor, coolant filter, blue spring update, in that order. Jmo

Sent from my phone that somebody didn't help me get.

X2. Don't bother with the banjo bolts. Waste of time/money mod

what they said.

I have had 6.4 banjo bolts in my garage for over a year now. Have had the engine apart 3 or 4 times to that level, and still can't find a good reason to install them. I would pass...

Well I would say they can't hurt and only help with the fuel flow to the injectors. I've spent money on worse mods.

That is exactly where the debate is. The claim is that the 6.0 banjos starve the rear most injectors and that the 6.4 banjos do not due to the larger bore and the removal of the check valve. That is, basically the debate is whether the 6.4 banjos enhance the flow of fuel to the injectors or not. So far I haven't seen any negative comments on them, but I also haven't seen any concrete evidence that they are needed. As far as I have seen, once the fuel spring is upgraded the 6.0 banjos perform their job at providing sufficient fuel to ALL the injectors, including the rear most injectors.

To restate, I haven't seen any concrete evidence that the 6.4 banjos have a positive or negative effect on our trucks. That said, if you want them then get them as they won't do any harm. However, you could also save the $20, or whatever the cheap cost for them is, and put it towards something else.
