Replacing V21 fuel lines

[spareparts]

if the old one acts like it may pull thru, I use a Yamaha fuel line coupling(plastic union) and clamp the new line to it using Oteiker clamps(low profile, you can find them at lowes in the plumbing department), use the old hose to pull the new one thru.

Oetiker clamps are what they use on high pressure fuel lines, more than enough on regular fuel lines(USCG app.). Make sure to use A1 line as your replacement
