Banjo bolt mod - Whats the gain?

What is the real, or perceived, gain from doing this mod? Does it make the truck run better or smoother? It's cheap and easy to do. Just want some facts before I spend a whopping $16. Thanks in advance.

Just helps remove restriction in the feed lines to the head.

Factory 6.0 banjo's have 2 holes in the sides, and a check valve. I modded my 6.0 banjos by enlarging the 2 holes with an 1/8" drill bit, and removed the check valve and enlarged the main hole. Doin it the way i did can sometimes weaken the banjo and it might break off in the head = no fun. I have had no problems tho.

the 6.4 banjo is just like the 6.0, but it has 3 feed holes in the side, as well as no check valve in the middle. More flow = more better.

You definitly want to do your research before droping that kind of coin . The gain is less restrictive flow of fuel into the heads, so your rear injectors dont starve. They dont have the check valves built in and have much larger openings.

I noticed no real difference. Just peace of mind at WOT that all injectors are getting enough fuel.

What the rear cylinders are really starving for is air. The flow tests on the stock mainifold make that pretty clear.

I did not know that, I find that interesting with a "pressurized manifold".
Do you think the "ZOODAD" would help offsett that?

Side note: I think you need to update your sig with the BPD oil cooler

I had to cut my signature way down for the links in it.

Doug at Gogo Diesel has a ported intake that really helps flow to the rear cylinders with before and after flow numbers. The problem is that all of the bolts holding the manifold to the heads run through tubes in the plenum inside the manifold creating a really unbalanced flow front to rear.

No the Zoodad won't help that but it helps with nice fresh air.
