I use my 10-12" abrasive chop saw on all sizes of braided lines, after I tape them with the correct tape. Then clean out the inside with a parts washer with mineral spirits before I assemble the ends.

Made over 50 lines easy that way. Makes a super clean straight cut and I use a tool I already own.

I replaced all my braided lines every 2 seasons, methanol is hard on lines.

One plugged nozzle caused me a torched block, piston and head not to mention everything behind the engine burned up. IE wiring, Data cables, trans blanket and much more$
I raced with methanol for 15 years, 8 with a TAD.

No front brakes and no throttle/rpm limiter.
