Perfect for simulating crimp-type end-of-line fittings on Blower injector lines, Injector Hat injector lines or carb fittings.
Can also be used as carburetor 'boosters'.
The photo above shows injector lines using Size A ferrules and .020" aluminum line.
Also shown is the blower restraint straps.
For blown engine injection lines, you'll need 16 for the injection hat and 16 for the blower manifold.
NOTE: ID sizes are 'tight' measurements and you may want to go up one size if you are at these measurements.
Here are links to the aluminum lines,, rubber lines and braided lines
Sizes are based on the ferrule inside diameter:
SIZE A - .021" ID
SIZE A1 - .025" ID
SIZE B - .031" ID
SIZE C - .042" ID
SIZE D - .052" ID
SIZE E - .055" ID
SIZE F - .060" ID
SIZE G - .076" ID
SIZE H - .078" ID
Each pack contains 10 brass ferrules, your choice of size.

VERY realistic looking pieces. Although the size .030 soft rubber line was recommended for size B, the line would not go thru the fittings. The price is very fair
[I inadvertently mixed a couple sizes together and I though I fixed this, but apparently not. If you find an incorrect size among your fittings, let me know and I'll send replacements - Ted]

As Ted says: using rubber line and these ferrules can save money and replicate the modern fuel systems. However, I've been waiting for size D to be in stock for a long time; also expect anywhere from 3-4 to be cut or crimped poorly. The sizes fit the rubber lines available very well.

Forget those seriously overpriced fittings for your fuel/brake lines! I've always struggled with the prices that are demanded for those turned alum A/N fittings, but once I was introduced to these tiny little fittings...problem solved.
Great idea Ted!

I've spent a lot on alum. fittings just to add detail to injector fuel lines in the past. No more. These ferrules (I use xtra small) along with .020 alum or rubber line let you plumb those top and bottom blower fuel lines for next to nothing. Best bargain and they look 1:1.
