dual feed fuel rail
 
Just decided i would build my own fuel rail after hearing about the tendency for the stock rail to run lean on cyl. 4 when using a afpr. After searching i found the thread that contained the parts and description of steps but no pics! And i know how much everyone here loves pics. So here are a few of my fuel rail. I did all of this for less than 30$ = win.

Parts:

21/64th drill bit
1/8th npt tap
4 5/16th npt hose barbs
1 5/16th elbow
1 5/16th "T"
4 1/2 feet of 5/16th reinforced fuel injection line
J.B. Weld
High Temp thread sealant
fuel injection T bolt hose clamps

I thought 1/8" npt was a 11/32 drill? Either way works I suppose. And I think we found it was the improperly routed coolant causing #4 to get hot and explode, not because it was running lean.

I'm pretty sure I saw Brain post a few pics as well as a how to thread on this, but yours has lots of a pics and what not. Props and thanx:)

This should be stickied

I like ur 90deg into the rail, but I opted for a straight entry to eliminate 1 more potential leak...and not sure whats up with the yellow, but good job/pics!

That I/C and FM box looks too familiar lol. Let me know if you need more piping. After I got done with my new setup I saw that I actually have extra

seraph 08-16-2009 01:32 PM

yeah i painted it yellow just for the simple fact that i didn't want anyone to think i was trying to copy FM or anyone else by painting it black, purple, etc.

LOL that is the same intercooler and thanks but i think i'm squared away on the piping. I'll post more pics once it get it in.
