Dumb diesel newbie question...

[Country Mav]

I'm new to diesel performance. Have had several diesel trucks through the years, but never played with them. I've built and raced many gas rigs though. BUT, here's my question- I'm seeing a "banjo bolt" mod in people's sigs.... What is this mod? What is the benefit of doing it? I'm just trying to learn all of this as I go.... Thanks! I'm sure I'll have many more questions! Thanks y'all!

the stock bolts have a check valve in them people are replacing them with the 08+ bolts which are larger and dont have a check valve in them. i guess thinking that it will be one else bottle neck in the fuel system? im not 100% since i havent done this mod but i would say its more for flow and not performance

08-10 6.4L Banjo bolts are much higher flow, they are far less restrictive, there are other companies that also make a after banjo thats even higher flow.

They keep your injectors happy, and dont starve the back injector.

As everyone has stated, they flow better... they're commonly swapped hoping that they'll extend the life of the injectors. However, no REAL proof has been documented. It's all in theory.

But hey, it's a very cheap upgrade! It's something I'm thinking about doing as well!

You can buy the 6.4 bolts, or remove the check valves and drill out the holes bigger.

Just installed my 6.4 banjo's and Blue Spring Regulator Kit. Definitely can tell the difference. Throttle much more responsive. Lazy dead spot from off pedal to on pedal is gone. Pretty cheap and easy mod for a great result.

I wish I could find out more about the 94 f 250 turbo and what to do to trick it out!!!!!!
