My two fuel rails are now complete. They are both 100% scratch built. They were made from 3/4" aluminum square tubing.

Three holes were drilled in a piece of square tubing each 118mm apart (This is the spacing of the intake ports on the 3.0L engine).

12 adapters had to be made that would fit the input side of the fuel injectors and would be brazed in the above holes. These were machined from aluminum on my trusty lathe. Anyone without a lathe doesn't know what he is missing. This has got to be my most useful tool for any hacking job. It all starts with a solid piece of aluminum stock.

The end product is the following.

A fitting was also fabricated where the rubber fuel line would be connected. This like everything else was brazed on using aluminum brazing rods. A simple propane torch was used to braze them on. I was somewhat skeptical about this aluminum brazing thing, but I am now a believer. This stuff works.

For the other end I picked up a 90 brass fitting from Home Depot. I was could also braze brass to aluminum with these rods.

Here are some more pictures of the assembled fuel rails:

Once complete I pressure test the fuel rails to see if any of my brazing joints had any leaks. The fuel rails were filled with water, and the fuel hoses and injectors were installed. The rail was pressurized to 120psi with my compressor. I found a couple of leaks which I fixed. Then I let it sit over night. The fuel pressure will only be 43psi in the car, so I should be ok.
