Does any one know if the 4g63 and the 420a share the same fuel line from the fire wall ? Or if its not the same line if the fitting at the end is the same diameter. I'm looking to pick up an adapter from DSM or buschur and I know most of there stuff is for 4g63s. Please let me know

Why do you need a new fuel rail? There's absolutely no reason to replace your stock one. Hahn runs a 10 second RS on the stock fuel rail.

I just want to replace the factory fuel line that comes from the fire wall to the rail with AN fittings and stainless line for easy access.

Both ends of our fuel rail will accept AN fittings but I don't remember what size. Like I said, you don't need to replace your rail. Every turbo guy on this board has done this with the stock rail.

The reason I ask is there is a AN fitting that I have seen that looks like the end of the fuel line,that rounded diamond shape piece with the o ring,and before I ordered it I wanted to make sure that it wasnt just for the 4g63 thats all. I mean I do have to replace my rail due to contamination and while I was there I figured I would upgrade the line and conection cuz those little screws are a pain.
this is what I am talking about

Eh, I disagree. I use a short -6AN ss line from the hardline in the engine bay to the -6an I tapped into my fuel rail. Leak free :7 It's not exactly made to fit, but it works.

What fuel rail? I think he's talking about the fuel LINE that runs from the hardline at the firewall to the rail. The link he provided are for adapters that attach to the stock rail and allow you to run AN fittings and SS lines. Either way, the adapters he is linking to won't work with our rail. BUT Dereks way is a good solution, or just buy some rail stock and have it drilled and tapped for -6an fittings.

Jeez are you guys half asleep.......

He wants top use the 6an adapter made for te 4g63 fuel rail. this is a question that gets asked once a year. it didnt fit last year and it wont fit this year!

Thanks guys

Yeah, Terry, I forgot that it is July again.

For the record, this is the third annual asking of this question. ;)
