I plan on replacing the 4 or five meters of fuel line on my Pik20E. I ordered samples of four or five quarter inch fuel line and inspected them. The Parker Super Flex 397 line seems of the highest quality by far. It is 6.4 mm inside diameter. I replaced the fuel lines on my Dimona quite a few years ago. I was able to reuse the original fire resistant sheathing. I likely used worm hose clamps, but now will use Oetiker clamps on the PIK and on the Dimona as it is about due again
