i'll be adding a sump to my gas tank and need to extend the supply and return lines to the sump. i want to know if i really need the koul tool to insert the hose and i can't see why i need special aluminum AN wrenches.can't i put these AN fittings on without these specialized tools.if i have to buy all these tools i might as well have a shop do the project.
 
You dont need either tool. However, tools are to make jobs easier and those tools do that job with ease. As far as the anodized wrench, they do make your fittings look nice, not like a crescent wrench which tears the anodizing to crap.
 
X2! Alot of people will wrap the hose with tape before they cut it. This helps cut down on fraying of the braided hose. The little barbs of braiding will scratch the anodizing if it comes into contact with it. Regular wrenches will work but you risk them slipping and marring the fitting and the anodizing. It can be done, just take your time and be careful.
 
If all else fails, read the instructions on the back of the package. Or search the internet for tips on doing this. It's not hard at all.
 
thanks guys! i didn't really think i needed them and i'm sure it would make the job easier but i guess if the fittings are lubed a little it should come together ok.i'm not worried about the finish getting marred or scratched a little.

if your not worried about scratching them then u will be fine ive done plenty this way, but like said above tape the hose before u cut it
 
Another method to keep the hose from fraying is to use a small hose clamp on each side of the cut line. This will keep the braiding from being pulled apart and fraying. What are you cutting it with?
 
Like everybody else said - its no big deal to put them together without these tools. The one thing I would recommend is a cable cutter to cut the hose - they have a hand held version at Home Deport for like $20. Summit sells a big one as an AN hose cutter for like $80 - uless you are doing something really big you probbaly can get by with the smaller one. I have cut all the way up to -12 with the little one - makes putting them together a snap! The smaller the hose, the harder they are to get together. Also make sure you lube them when putting them together - much harder withour it.

get a set of cutters and dont look back. Agree with what everyone else said about wrapping tepe around the cut area prior to cutting.

i'll look into the cable cutter.how do you think a dremel would work with a cutoff wheel?

I used to use a cut off wheel on a grinder but since I picked up some cable cutters I don't even need to use tape anymore.
 
the dremel will work, but you risk getting shit in the lines. ive used a razor blade and the black nylon prolite with good results too
 
All good tips here. No matter what method you use to cut (Cut-off wheel, cutter, chisel) ALWAYS wash the completed hose out with solvent and blow it dry! Debris from the cutting operation AND installing the ends can kill an engine. In a fuel line, it's usually limited to sticking a float or something at exactly the wrong time!!
