More CNC Fun - Fuel Rails

[a930pilot]

As I'm collecting parts for my EFI project, I decided to make some fuel rails.
I know that the stock rails are fine....I'm just having fun.
The raw rails are -8 and will use a -8 port fitting for -6 lines.
In the end, I determined that I need to try again as the injectors were much too tight in the bore and I had a hell of a time with the stainless steel brackets.
I have a bunch of laser cutting that I need done, so, I might just add a few brackets to the job.

Very clean looking, good job.

Those look great.

You should make another set and send them to me for long term testing!

I'll 2nd your LT test.

Thanks guys, I guess I'll have "several" brackets cut!

I do have a question...I milled the injector pocket with a 13.5mm end mill and can only get 1/2 of the injectors to go into the bore. Yes, there is a chamfer. Is it possible that the old injector seals just aren't compressing enough and keeping the injector from inserting?

I think the OEM fuel rail injector pockets are tapered, not square.

This states 14mm. I'll buy you one of these if you make me a set.

Since I was going to need injectors anyway, I ordered some 60# Deka and they were a perfect fit. I guess the old O-rings were just not soft enough.
To those that wanted to test them....I made an extra pair. Beware that these were designed for the Carrera intake!

I'm up for a set if you end up producing these.
