After reassembly of a truck after putting studs in I was thinking of putting the upgraded banjo bolts in untill I looked at the stock ones,, didn't take much thought or work. Took the stock bolts and just used a bench grinder to remove most of the material off the face of the bolt then used a belt sander for the fine finish of the end of it so the spring and core would come out along with the plunger. clean it out with carb clean and air and just make sure it is deburred. took a total of abot 10 minutes and is alot less restrictive. anyway to save a buck

 

Or just remove the internals by taking the clip out... the internals will just fall out of there haha.

You can drill the holes larger too, besides just removing the internals. A lot of guys did this before the 6.4 bolts, but I've also seen a few stockers broken off in the heads too... the 6.4 bolts are cheap enough.

It can be done though!

 

I've heard that the down fall to this is that the check valve removal:
1. Has no measurable performance gain.
2. Allows for the fuel in the rails to drain back when the truck isn't running.

Curious if this isn't inviting air into the system, causes harder starts after long periods of inactivity (having to re-prime the rails), or any other adverse effects like that?

 

Really don't see how it will drain up to the bowl because it would have to have air on back side of it to be able to syphen. if you see how much space is taken up by the plunger it is an obviouse obstruction when trying to pass more than average amounts of fuel through it.

 

No different than the 6.4 bolts everyone is using. No measurable performance gain is true, but it's just eliminating the biggest restriction in the fuel system. One of those peace of mind mods. The fuel pressure will drain off, but it will do the same thing with the stock check valves, since they're not a "true" check valve. I had to replace them with real check valves when I installed my vegistroke, the stockers will leak back.

Yeah it certainly wont hurt anything. Anyone with a fuel pressure gauge can watch it lost pressure when you shut the truck off, but you can also watch pressure come back up when you turn the key forward too.

 

Maybe I should have left the stiff Gillette spring in and swapped in 6.4 banjo bolts onstead of a blue spring.

One other thing I was told was that using hollow banjo bolts would allow for a program that added more fuel. Now that made sense to me.

After the trans job I did last week, I think I'm good on spending money/working on my truck for awhile!

 

Why do you say that about the gillette spring Karl? The banjos don't change pressure, rather volume when RPM increases and a higher volume of fuel is desired.

 

I say that because the Gillette spring didn't give up as much high rpm pressure as the Blue spring does.
