Boost reference FPR - vacuum line routing?
I have a Aeromotive boost ref FPR and built a return style fuel system which leverages stock rails and truck mani from a 2004 LS. Plans are to install a windmill by the end of the winter but for now I'm interested in getting some of the basics covered.
Question is where do I plumb the vacuum line for the FPR? I think it's to the pass side of the truck mani right? I'm pretty sure I saw a sloppy vid where he cut off the end of a capped port and plumbed a MAP to it but I'm using the stock location for a 2 bar map and was thinking I could run the FPR and a gauge from that location. Just thought I'd check here before I did.
Here is my problem...... I'm a total newb at Fuel Inj, Forced Ind, and LS in general so I think the capped port on the pass side of the intake mani sees vacuum but I honestly don't know. I guess if there is a better spot I'll take that too!
The more I thought about it I have more vac lines needed as well like say the WG for example!
