Home made fuel rails, This was not easy...I am not a machinist Options

[Als914]

Hello all. Thought I would share with the group the final results of my weeks of research, machining, drill tapping, thread cutting and assembly of my home made fuel rail. Unfortunately I didn't take pic's of the various steps but only the finished product. The rail are aircraft quality extrusion blanks. I decided to use brass fittings in my first attempt because it is less expensive than race fittings such as Russell performance

I didn't know how the fuel rails would perform so I used a great deal of caution at all steps of the process and mostly at engine start up. The only leak I experienced was at the exit end of the driver side rail due to (of all things) a mismached end fitting, the theads didn't seat propperly. BTW, I don't know if you can make it out in the pic's but the rails are bracket mounted to the injector hold down bolt and stud.

I now have over five hundred miles and days of 100 deg's on them plus some very hard driving, so I feel comfortable that they will continue to perform well.

Very nice work ! Do I see brackets in one of the pics ? Is the fuel pressure gauge tapped into the fuel rail ? Are the hoses from the rail to the injector straight or bent ?

Yes Jim, the rails are mounted via brackets attached on top of the injector clamping ring, plenty of thread on that stud. of course I had to modify the bracket attachment point to fit within the top of each injector clamping ring. The rails sit just above the top plain of the air intake tubes.
I drilled and tapped at 45 deg. from perpendicular center, installed a 90 deg. street elbow and mounted the gauge to the elbow for ease of viewing.
The injector hose exits at the bottom of the rail via a 90 deg. fuel hose fitting and the hose is looped down to connect to the injector. I have read some where that that lenth may be too long ( mine are about four inches ) but this has proven NOT to be a problem. My next set will look much nicer.
BTW, the trunk shocks I bought from you look and work great. Thanks.
