Make a fuel rail

[siteunseen]

I've found -6 size aluminium fuel rail stock on e-bay for $10 a foot, 2 feet + shipping $35, and can get the 5/16" x 1/4" male barbs for about $2.50 then the 1/2" size for the 2 ends, couldn't be more than $4 each. Can borrow taps and bits from Pop. $70 dollars or round about and Pallnet guy on Hybridz wants $155 for a great looking fuel rail I think I could make without the fancy lines machined into it. Anybody ever done it? Is it harder than I think? I know I'd have to use that clear sealer instead of teflon tape.

Pallnet is first class and saves the headache and risk of errors when learning on your first rail. Plan to drill and cut two.

If you want to improve on the design, source extruded aluminum with two internal passages for send and return and integrate an fpr in one end.

You can also use the stock rail, cut it and bubble flare the ends or braze barbs on the ends: It will look like this:

Cool. I'll have a spare.

A friend of mine found this site http://www.rossmachineracing.com/dash6.html

That's the same company I'm looking at on e-bay. They have "scratch & dent" for $5 a foot also. I think I'll listen to Blue's advice and buy the cheaper for a study guide and the good stuff for my finished fuel rail. Thanks for the heads up.

I was thinking order a 6 ft of dash 6 material. for my new rails.

Do it! I think with a drill press and some drill bits and thread taps it would be easy. Looks like 1/2" on the ends and 1/4" threads for the injectors and cold start. 5/16'' barbs. Thread 2 holes on the bottom for the mounts. I am thinking of mounting my Fuel Pressure Regulator somewhere around the heater hose in & out on the firewall and run the return line from the FPR straight down to the metal line back to the gas tank by the vacuum bottle. Shirley we can do it.

For my Z is less complicated, because my Z gots megasquirt

I wish I could say that, less complicated. I hope it turns out like you want. "Megasquirt" that's a funny word. I'm going to read up on those.

Here's the fuel rail that looks better. http://www.azspeed-marine.com/furaex.html it's finned or milled. Whatever, but also read "Milling fins into any surface will increase the available surface area for heat to dissipate from. Increased air flow across the fins would keep the rail cooler."

The fins are great for transferring heat from hot to cold. In the engine bay, hot is the engine and cold is the fuel rail. The fins will result in hotter fuel not colder.

Just something to think about.
