After slowly recovering from the late night celebrations, I thought I would sneak out to the garage for half an hour to assemble the fuel rail and injectors in the inlet manifold.
I wanted to use the injector loom from the old 320i engine because.....
a) it was already modified to connect to the Auotometer water temp sensor and, b) I know it works with the rest of the engine loom already installed in the car.
After assembling the fuel rail and injectors, I then discovered that BMW had changed the design of the fuel rail between '88 and '89. The early fuel rail has a fuel hose connector at the rear of the engine which clashed with the new type loom.
No problem, I thought, I'll just swap the fuel rails, so whipped the old one off the 2.0 litre manifold. Whilst checking it over I discovered that the 2.0 litre fuel rail has a 2.5 bar regulator whilst the 2.5 litre has a 3 bar. So I had to swap the fuel regulator as well.
About 2 hours later, I finally got it all assembled!!
Happy New Year!
