The easiest and probably a cheapest way to accomplish this is with a factory fuel filter/regulator built into 1 for the Corvettes. In my best Mad Max Thunder Dome chant "2 lines enter, 1 line leaves, 2 lines enter, 1 line leaves..." I picked mine up for just over $40 shipped:

Eventually, I will post of a detailed parts list with part #'s and costs for every off-the-shelf part I used. I have it in an excel file, but it won't be complete until I have it running.

Been working on the AC lines...

I used a cut off wheel to remove the oem crimped hose clamps from the LS4 compressor end as well as the Fiero chassis aluminum hose ends. Then It was a matter of cutting the new A/C barrier hose to the proper length. Here are some pictures of the test fit:




While searching for the ferrules for the ends I came across several types for the OEM bead lock (the ferrule is locked between two beads on the fitting) fittings. Most of them required a larrger hole in the ferrule so you could push the ferrule past the beads and use a c-clip to retain it. I am sure those would work, but I also found some that had the larger hole offset:

So these just slide into place, fit in-between the beads, then when centered by the hose they are locked into place. Pretty slick setup, so that is what I am going with. You can buy the ferrules in packs of 25 for each size and they come to about $1 per ferrule. So I am buying 25 of the #8 and #10 and will likely sell the left overs in the mall.

Here is a nice how-to on using these ferrules. It covers removing the old hose and assembling the new one with these ferrules:

For crimping these, I am planning to just take the assembled hose with new ferrules to NAPA and have them crimp them for me. The other option is to buy a crimping tool... but they are about $150 for the cheapest one and I don't build A/C lines very often. One of the most compact crimpers I have found is the ATCO 3300 Handi-Clamp:


You can buy the whole tool with the dies for $155 from here:

Or you can buy just the 2 needed dies (#8 and #10) and use a large bench vice to compress them. The dies are only $20 each from here:

The cold air intake is pretty much done. Just need to sand it down and paint it.


I ended up putting a small notch in the air intake to avoid bending the shifter cables:
