Let’s Build a Fuel Rail

Build034 1974 BMW 2002 M10 Turbo 30

This M10 2002 with mechanical fuel injection would not work with Microsquirt. We had a choice to make. Either run a different intake manifold, such as the e30 318, or make the tii manifold work. We wanted this to look at orignal as possible so the latter was chosen. To make that happen we had to weld injector bungs into the lower intake manifold (yay, tig weld 50 year old cast aluminum), install some shorty injectors, modify a fuel rail, install a Fuel Pressure Regulator (FPR), and fit it all down inside the tii intake manifold. Follow along below as we solve problems...or scroll to the bottom and just dig into the gallery. Enjoy -jb
