It’s always nice when plans come together. I was browsing a VW forum recently and was reading about the risks of engine bay fires, often caused by out of date fuel hoses that do not meet current safety standards. It just so happened that Machine 7 happened to be running a great bundle deal on an essential kit to replace older style cloth braided fuel hose with the safer modern SAE J30 R9 grade, plus fuel filter and 10 correct hose clips for this hose. The bundle contains 3 metres of hose, which should be sufficient to replace all of the flexible hose normally found on all air-cooled models
Over recent years, fuel at the pump has been replaced with a grade referred to as E5. It contains a 5% mix of Ethanol. The Ethanol mix is better for the environment, but unfortunately degrades rubber fuel hoses. There are current government proposals to change unleaded fuels to E10, with 10% Ethanol. SAE J30 R9 fuel hose is designed to withstand the level of Ethanol in E5 and E10 fuels.
Fuel hoses should be checked every few months, and replaced, if there are any signs of degradation. We believe that anybody using the old style cloth (or stainless) braided should now upgrade to the more modern higher specification. It is far better to be safe than sorry! The hose has a 5.6mm internal bore, which is ideal for all standard installations as well as most twin carburettor set-ups, so perfect for my twin Dellorto carb set-up.
Once ordered online, Machine 7’s now famous prompt delivery service took care of the rest. Now all I need to do is fit the new hoses to upgrade my fuel pipes in the engine bay… the trouble is, once you start thinking of upgrades in the engine bay, other ideas also start springing to mind…
