Modern Vespa

Hi, newbie here. I need to replace the line to the bottom of my 2007 LX 150 fuel and am wondering how to remove the original Vespa clamps on the lines. Any thoughts?
Thanks.

Hi. Left of 'valve' after 'fuel'. Apologies

Snip them off with wire cutters, they aren't reusable. Replace with appropriate size of "worm drive" screw clamps. The cheapest lines of these clamps are abominable - they strip, rust, and break. The best of them are expensive but usually worth it - the grooves for the worm drive to grab are not cut all the way through the clamp. But the most important thing is to buy the right size: huge diameter clamps don't seal properly on small diameter hoses.

Avoid the kinds of clamps that pinch on and off with pliers, they're brittle and don't seal well. Do not use zip ties as substitutes either, they are not strong enough.

You can wiggle a screwdriver between the clamp ends, and it should pop open.

Spring clamps are fine for replacing them on the fuel lines, but not coolant lines. For those you need solid clamps with rounded edges such as these: https://dupageproducts.com/portfolio/metric-smooth-band-hose-clamps/

(Jubilee clips in the UK - the actual brand that is. )

Get a set of these for $2.00. Once done you'll wonder how you lived without them.

^^^^ They are incredibly useful!

Well that was easy. A friend had told me that they were difficult to get off. Whata rube. I just attacked it with some side cutters and it basically self-destructed.
Thanks for all the timely help. This is a great site you got here. I'm having a good time reading what you all are up to.
Cheers.

Since the original clamps on the coolant lines don't have rounded edges, why would the replacements need them?

better safe than sorry. so stainless steel, rounded edges, and no holes along the length of it (just the ridges for the screw). They are still cheap enough that it ain't worth skimping (if you find a decent supplier that ain't ripping you off)
