Allstar PerformanceALL11081 Koul Tool Kit for -6 AN to -10 AN Fitting/Hose

Works as advertised! A must have with steal braided fuel line! Easy to use

I don't normally write reviews, but I had to with this. I have been putting together AN fittings for years and I thought I had it down to a science. I bought this and thought - might as well give it a try. It took me less than a minute to do an end without the stainless wires poking me and drawing blood. Even if you hose is a little frayed, it still works great. I am going to by the other sizes I need now.

The man who invented this is a hero. All my AN lines were leaking and had taken me hours to do. I bought this little miracle worker and took me minutes. Watch the install video on YouTube and bang done. You don’t need a vise. I showed how I did it. Absolutely effortless

I know their website says it doesn't work on Evil Energy products but as you can see it works just fine, lines are pressure tested and passed. The use of super glue on the braiding can help on stubborn lines.I stumbled across this product by accident but I'm glad I did, being disabled this helped me greatly.

Adding an external trans oil cooler. Decided AN fittings were a better option since existing steel lines required cut and splice with hose always seeps down the road and worm clamps against barbed fittings always eventually cuts into hose.Tried first fitting, all -6’s, and although eventually got steel hose into nut it was as expected a pain in the …. Took about 20 min. And poked fingers.Decided on this Koul Tool to expedite installation and save my fingers.As instructed in on line videos prep line, insert nut, shim as required. I did not have a vice available so all with brute grip force for assembly. It took about 3 minutes to get line into fitting. HIGHLY SUGGEST to use vice as in OLV. Great tool, saves time and fingers!

Great, simple design that makes the process of inserting the braided hose into the fittings painless! I have never attempted to make them up without the Koul Tool, but had this tool recommended by a mechanic friend who told me how much it helps. So, when I bought a valve cover breather kit that used -AN fittings and would require me to make up my lines, I purchased this tool. There are videos on YouTube to show you how to use this ingenious tool. I measured the hoses to length, marked with black electrical tape (key step in the process), used a 4" grinder with metal cutoff discs to cut my lines (cutting in the middle of the electrical tape--the tape keeps the line from fraying & keeps things together when putting in the fitting). Put the Koul tool in a vise (it looks like plastic, but it's a resin that is VERY resistant--the stuff is TOUGH), I dabbed a touch of 5-30 motor oil on the outer surface of the tape & fed the line in using a twisting motion. You may have to watch to see if you've got the line all the way in. When it's in place, put the fitting in a vise (I recommend these to keep from marring the anodized aluminum fittings: http://www.amazon.com/gp/product/B008BF1VEK/ref=cm_cr_ryp_prd_ttl_sol_5), dab some oil on the fitting threads and wrench the fittings down.

The product itself is well made, but so far it’s not been the miracle expected for joining the AN fittings to the braided steel hose.

I use these for AN fittings to make braided lines.Have you ever had to put the hose into the hose end fitting with out killing your hands, the hose, or the fitting. These things are super EXPENSIVE but save you a ton of headache. I recommend these if you're going to make custom lines for your car, or whatever.Also pick up an set of aluminum wrenches  Allstar Performance ALL11120 Double-Ended Aluminum Wrench Set  . Don't be a hero and make lines with steel wrenches. They will look bad, you will destry the fitting.The only wacky thing about the Koul Tool is that sometimes you will have a fitting that is too big for the one of the tools. I found that you can still wedge it in and clamp it with the vise. It works everytime.

Does what I hoped it would do by making the difficult AN fitting slide onto the Braid Line with GREAT ease..YaHoooooo.

Makes life a lot easier when inserting braided fuel hose into the fitting.

You dont need these things, and they are not cheap, bt they turn an irritating job that is easy to mess up into an easy Job that almost can't fail.Normally I don't buy tools that are optional or that just make things easier but can be done without. This is an exception, will buy other sizes if I use those hoses for sure

Easiest way to assemble AN hoses ,makes a tricky job a lot easier,but your gonna need AN wrenches as well if you don't want marred up fittings
