Hi @all

I want to change the S4 sec alu fuel rail into my S5 Engine...because I want to install the aeromotive fuel ...so the problem...I have seen that my S5 fuel rail has 2 vac lines and the s4 and the aeromotive reg has only one vac line ...for what is the second vac line on the sec fuel rail....could I block off it and which one of the two lines?

thanks olli

use some washers as spacers for the bottom of the rail. bolt the s4 rail on. run the vacuum line to the fpr. done.

why are you using the s5 rail? why not use the s4? the s4 only has 1.

it must be something with your euro spec engine...the usdm (and i believe jdm as well) only have 1 nipple.

I want to use the S4 Alu Fuel Rail( with the an6 adapters to m12x1.25 & m14x1,5)...it has 1 vacline for the FPR...but I have the S5 Engine ...and there are 2 vaclines for the orig. sec rail...that is what me confused...which one I have to cap/ block off??

Your picture... is this your s5 rail?? my original rail has two vac lines and two fuel flanges
