I got my 2013 TVS kit on Friday and immediately started looking over the plenum to see how I was going to attack the vacuum port issue. For those that don't know, the 2013 plenum has only one vacuum port, but it has a provision for a sensor that the 2007-2010 GT500's don't have. Most guys were just blocking that hole off and using a series of "T" fittings to get the extra vacuum line hooked up. I didn't like the idea of having a bunch of "T"s floating around back there and I really wanted to keep the nice factory push lock adapters on the hoses. Obviously the "T" fittings work, but it just didn't look as clean as I'd like with all the hose clamps and fittings. So, here's what I did.
The hole in the back of the plenum for the evap sensor is the perfect size to use a 3/8-18 NPT tap to thread it. There wasn't any drilling or enlarging required, I just lubed up my tap and went to town. It took about 10 minutes, taking my time and cleaning the threads thoroughly, to get a nice clean thread inside the hole. This picture shows the hole after I cut the ears off and tapped the hole for the 3/8 NPT brass fitting.
Once I had the threads clean and the ears ground down flat and clean, I coated a 90* 3/8 NPT to 3/8 nipple with some RTV gasket maker and threaded it in. It fit perfect.
The next step was to salvage a push lock fitting off of the factory fuel rail feed. The FRPP kit comes with a new fuel rail, so you won't need the factory rail with this kit. So, I cut the push lock fitting off the rail with a dremmel and then sanded the cut end down clean so that it wouldn't have any burrs or sharp edges. This fitting looks like it's slightly larger than the one that's on the factory plenum, for the vacuum line that is going to be hooking to it, but it works perfectly.
This next picture shows where the push lock fitting is going to be and how it's oriented. It fits into the push lock fitting perfectly and locks into place the way it did on the factory plenum.
Finally, with one small 3/8 hose clamp and a few zip ties, the modification is complete. You can now use the factory push lock fitting on the vacuum line without cutting any of the factory hoses, no added "T" fittings or clamps and best of all, nothing else needed to purchase. You can do this by simply salvaging some of the parts that you would ultimately have been tossing anyway. Just one 90* 3/8 NPT fitting, a small length of hose and one hose clamp is all you'll need to have/get.
I'll update this thread as I go with the install of the rest of the parts. The blower is pretty straight forward swap. Very simple and everything fits perfectly. For reference, the blower bolts are torqued to 30-35 ft.lbs. in an inside-out rotation (starting in the middle and working out, jumping from one side to the other).
