Yet another good reason why NOT to buy an ex rental....
I have had my KZ for 8 years and have never found anything remotely that bad... I really hope it was added after the fact and not by KZ...
To the OP , you could also get your measurements together and go to a hydraulic line shop and have them custom bent to the exact lengths and shape... They will bend , flare , whatever you request... We use them when repairing our forklift's hydraulic lines when they rupture... A lot cheaper than buying from the pre made hose from the manufacturer...
