for those that have done the BB mod then the blue spring..

well, i decided to order the blue spring kit to change out my BB modded set up i had. i was running about 49-65 psi before and then i go throw in the blue spring and now i am running 39-53ish. i have a quadzilla commander and it has a fuel pressure adjustment setting in it so i pretty much have to take what it says with a grain of salt. until i can compare it to a real gauge that is. plus, i read the psi off the passenger head fuel rail. but without a doubt, it dropped from what it was. anyone else do this swap back to back and if so, what did you come up with.
thanks
clarence

never mind. just was a dumba$$ thats all. forgot to put in the oring that goes in behind the little black insert that the spring goes into. put that in, pressure is up to around 55-65, maybe see 48-9 when i romp on it. still not happy so maybe i will try the blue spring and the BB.

the acronym "BB" may represent "banjo bolt" but in this instance the BB MOD has nothing to do with those bolts. It IS simply adding a BB (like from a Daisy BB gun you shoot the neighbors dog with when he is pooping in your yard) to the end of spring in the fuel pressure regulator to lengthen the spring and therefore increasing the fuel pressure. The Blue Spring Mod is essentially the same procedure because it replaces the stock spring with a stronger/longer one, tho it costs a bit more than a single BB!

no thats not it. its a actual bb from a bb gun in behind the spring to increse the cracking pressure and up the fuel psi.

BTW, just a FYI to the newbies. It's not recommended to do the BB mod unless you have a Fuel psi gauge!! Depending on your current spring condition, adding the BB may push the Fuel psi too high!!

Oops

Seems like the blue spring and banjos go hand in hand, so I jumped to that conclusion
