Hi, Following on from the topic about R9 fuel hose breaking up, here http://thelatebay.com/index.php?threads/r9-fuel-pipe-breaking-up.36508/page-2#post-692586 Here is a good article for the breakdown http://www.groups.tr-register.co.uk/wessex/ethanol-update.html I bought my R9 from Advanced Fluid Solutions Ltd which is not stamped with a brand. What are the alternatives? Volksbolts have some codan R9 line http://www.volksbolts.com/faq/fuelhose.htm Interesting article from the hot rod site http://www.hotrod.com/techarticles/engine/hrdp_1101_performance_fuel_hoses/viewall.html This company seem to sell Gates Barricade Fuel Line Hose & Goodyear line which seems to get good reviews, this meets SAE J30R14T1, I think this will be the next one I buy http://flexiducting.co.uk/automotive_hoses_26.html or webcon E10 http://www.rallynuts.com/motorsport...ebcon-nitrile-rubber-fuel-injection-hose.html Goodyear link http://www.goodyearep.com/ProductsDetail.aspx?id=17700 Gates Barricade link http://www.gates.com/products/autom...l-system/barricade-carburetion-fuel-line-hose Marine fuel linem seems to suffer but not as quickly http://www.hoseworld.com/acatalog/automotive_and_marine_hose.html or one last option is to find a suitable nylon fuel line like they use on the modern cars from the tanks to the engine bay. I dont know how this would work with the engine bays heat from a bay. Anyway thats all for now, any thoughts?
