I corrected my valve clearance today, so I had to disconnect the main fuel line from the tank (the one that is connected straight down and has some metal wire as protection around it). Unfortunately the line ripped. At first at a 90 degree angle, then when I tried to connect the remaining line, it ripped a full 5 cm inward. So now it is useless.
I was wondering if anybody knows if silicone tubing is petrol resistant, so I could use that safely until I get a original spare part.
I use vinyl hose for draining the lawnmower oil and I'm pretty sure vinyl lines are used for small engines like weedeaters. That might work for a fuel line, just not sure how it would handle the heat. Wouldn't a regular fuel line from the auto parts store work? It wouldn't fit in the metal coil sleeve, but it should work fine for the fuel and the heat.
Don't use silicone hose. Apparently it swells and can weep gas or something like that. Get a short length of fuel line from an auto parts store to use temporarily. It could work permanently, but it won't have the factory bends in it.
As I was trying to fix it with the fule line that I got (inner diameter fiiting the tap/petcock properly), I discovered that on the carburettor end, the diameter is significantly smaller, to an extent that it cannot simply be overcome with tightening a hose clamp. There is hardly any space for a hose clamp, by the way.
So I went back to the autoparts store to get a smaller size, as well as an fuel resistant adapter to be fixed between the two hoses. I decided to use a long piece of the narrow hose, and just a short part (about 6 or 7 centimeters) of the wider one that fits to the petcock. The adapter is slighty wider than the narrow one and a bit smaller than the wider one. So I end up using four clamps. One on the carburettors end, two on the adapter and one on the petcock.
It will probably do the job, but I am very much in doubt about the esthetics. If it looks bad, I am going to have to order the orginal hose, that apearantly lasts for about 20 years.
