Fuel Line Replacement, Tunnel Clips? How? Plastic? Options

[DaveO90s4]

Hi all, as a preventative measure I've decided to replace the plastic fuel lines in '75 914. I'm running carbs and a low pressure fuel pump. Plastic lines that came out, 40+ years old, were in good condition.

So I read up the on line literature and it seems stainless is the way to go (e.g. Tangerine's product) but it seems that it is important to fasten stainless lines at regular intervals to prevent work hardening and cracking through vibration.

But I see no information at all about how to actually fasten the length of line that runs through the tunnel, so as to prevent work hardening. It simply does not look practicable to do so.

If the 'old' plastic lines lasted 40+ years I'm tempted to use new plastic lines - provided I can get some of the same OEM quality that are NOT made in China (I am so so over buying f*&^&ing crappy chineses made 'quality junk).

So, unclipped stainless or OEM plastic (remember, low pressure carb'd system).

Thanks

Dave

PS Buying from Tangerine / other US supplier is not an option - the cost to send a few sticks of 8mm tube to Australia is cost prohibitive.

The PO had removed the clips in mine and I just recently replaced the lines with Tangerine Racings SS lines.

Can anyone provide a suggestion to anchor them?
