My truck is in the shop getting arp's,, egr delete and oil cooler. Is it worth it to do the banjo bolt mod or a bad idea because of no check valve in the 6.4 bolts?

There is a check valve in the 6.0 banjo bolt and not in the 6.4 bolt. The reason for replacing it is for better flow but the check valve must of been in there for a purpose. I know some guys on here have done this and just would like to know if it helps or just one of those useless mods or a harmfull one.

The 6.0L fuel banjo bolts have a check valve inside them. This is supposed to prevent system spikes. For the 6.4L trucks the fuel banjo bolts do not have the check valves. The 6.4L bolts end up having a larger opening to feed fuel to the rails. So people will "upgrade" to the 6.4L banjos.

When used with the updated fuel pressure spring (blue spring mod) it's a move towards improving the fuel system. Add to that a AirDog system to provide clean air-free fuel and your injectors will live a long life.
