Modification Of The Factory Rb26 Fuel Rail - Questions On Reliability, E85

[The Mafia]

I don't want to turn this into a debate. Just doing this to make it neater and have the ability to mount an aftermarket regulator in the factory position.

did you ever look at something like this?

Sure have and I'm already running one. The issue is that these size the hole down to less than 6mm. I want -6 all the way (8mm)

-6 JIC on each end just works really well, while keeping the factory look and making it even neater.

fair enough, good point

Is the factory RB26 fuel rail even zinc plated, I was under the impression it was cadmium plated from  the factory, like the fasteners. Am I wrong on this?

Who cares. if upgrading size of fuel line get a aftermarket rail. they are cheap.

I actually wanted to know for replating purposes. I am restoring a GTR and I want everything as it was originally. The only NOS rails I see available are for R34’s, and the plating seems different every time I get one. Some are blueish, some are silver/gold, other very gold. Cadmium was used extensively when the skyline was being produced. I’d like to know the real plating was

I'm making 500awkw on e85 with a stock fuel rail and even egts. Don't over think it.

so you don't need -10 fuel lines with twin dual entry rails for 400awkw on E85 then? ?

Getting someone to cad plate might be a bit difficult! Last time I had need of that, probably 25~30 years ago, the plater lost half the fasteners in the tub and it was a heavy metal nighmare even then. He's long since dead and out of business, expect aviation use might be the last holdout - if you can find someone who does that as a sideline - if it simply must be cad.

Gold passivated zinc plating is what I would have expected even back in the 80s on jap cars though.

I run -6 lines for my e85 setup with 2x walbro 450L pumps, and billet tank lid. Around 600whp. Some say too small, but meh, no problems yet.

I’m still trying to determine what the original plating is. The new rails I get all appear to be R34 rails, and the plating on each one is different than the next. Blue, purple, silver, faint gold, but no yellow zinc. I have no idea what the r32-r33 rail looked like originally because I can’t find a NOS one, or a one that is not corroded. Cadmium platers are not that hard to find in the US.
