teddan Posted July 30, 2013 Share Posted July 30, 2013 my big AN hose from the tank to engine smells a little bit of fuel if you smell direct on the hose(without pressure). No leakage, even in 50 psi. seems strange? Quote Link to comment Share on other sites More sharing options...
hodge Posted July 30, 2013 Share Posted July 30, 2013 Are you using rubber or Teflon lines? Quote Link to comment Share on other sites More sharing options...
teddan Posted July 30, 2013 Author Share Posted July 30, 2013 no ide mate. It was fitted before I bought the car. Maybe it is just normal rubber hoses with steel braid? Maybe I should buy this instead? "This stainless steel braided hose consists of a teflon (American Dupont) extruded core with a heavy duty, protective, full stainless steel (grade 304) braid on the outside, making it exceptionally lightweight, flexible and durable. Even better, the hose is designed to handle any fuel (including methanol, E85 and nitromethane), oil, coolant, brake, transmission, powersteering fluids and nitrous oxide. The Telfon PTFE core makes this hose significantly more durable and longer lasting than standard rubber nitrile stainless steel braided hose. This hos can be used without hose fittings and secured over 15mm (max) barbed fuel filter/pump OE solid fuel lines with the use of hose finishers / jubilee clips. Temperature range from -73 degree C to +232 degree C." Quote Link to comment Share on other sites More sharing options...
Lee P Posted July 30, 2013 Share Posted July 30, 2013 Teflon hose is better and will not give off vapour like the usual braided line. Its alot stiffer though so can be tricky to run and the fittings can be a bit more pricey. Deffinatly worth it though. Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted August 2, 2013 Share Posted August 2, 2013 Rubber lined braided fuel hose will smell a bit, due to osmosis through the cell structure of the rubber. As LeeP says, if you can manage the restricted bend radii Teflon lined hose is better if the smell bugs you, or frightens your passengers.

marc_p Posted August 2, 2013 Share Posted August 2, 2013 or frightens your passengers. I have a slightly leaky oil pressure sensor in the 944 which gives a whiff of oil if you put your foot down and the other day when I had a passenger in the car, I also had a bottle of water, so when they asked about the smell, I chucked them the bottle of water and said 'oh, it's leaking oil and might set on fire, if it does use this', their facial expression was priceless Quote Link to comment Share on other sites More sharing options...

From my point of view very small chance that this can ignition? Edited August 2, 2013 by teddan (see edit history) Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted August 2, 2013 Share Posted August 2, 2013 No, seriously,unless the fumes are such they give you a headache it should be OK, that's the downside with rubber lined braided hoses used for fuel lines. I believe some of the very latest liner materials do not suffer osmosis, but they are probably specialised and expensive. Teflon lined is best, but a pain if you need to get it round tight bends. This is one of the reasons you will find very little length of rubber in stock fuel lines. Quote Link to comment Share on other sites More sharing options...

My entire setup is done that way, and I NEVER have any fuel smell inside the car. Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted December 30, 2013 Share Posted December 30, 2013 It'll probably be worse. You need Teflon lined hose if the small is objectionable. Quote Link to comment Share on other sites More sharing options...
