When using the vortech FPR, should a vacuum line still goto the stock FPR or just leave it alone?

 

yes a vacuum line still goes to the stock fpr if you're using a vortech fmu, you can tee it from the same manifold source. I think vortech makes fpr's that replace the stock fpr's, but I think your refering to the fmu.

what would happen if I didn't put a vacuum line on it? cause I haven't had one on it since I put the turbo on...but I still get good vacuum. but other things are kind of weird.

All that'd happen is you wouldn't be getting the lower fuel pressure during higher vaccum situations. Pretty much any non-acceleration driving would have a high fuel pressure. It's possible the ecu could correct for the added pressure, but you might as well just T off of another vaccum source & make the FPR earn it's keep.

ok, thanks
