Plenum Vacuum lines... - ZR-1 Net Registry Forums

LGAFF · 03-25-2009

In chasing my plenum vacuum leak, I ran across hard emission lines sold in a packet at Autozone. The line is slightly bendable and I found that if you take a hairdryer, put it on high heat you can mold the lines to the same configuration of the originals and use the factory fittings. UPon heating, you can twist the line, turn it with 90 degree bends and it stays formed in that position.

Once I heated the line, I held it in place and then switched the hair dryer to cool to help the molding process. Obviously a heat gun would work better, but this worked well. I also noticed that Dorman sells a three way check valve just as we have under the plenum.
