Hi

I've been contemplating changing my fuel lines (at the engine end) for braided stainless ones, but I've heard there can be some issues with these.

Does anyone have any experience - good or bad?

Good, but make sure they are ethanol rated.

Don't buy the cheap and nasty stuff, on most dual carb setups you can go AN fittings but it can work out expensive to do it properly.

Flexible hose has to be ethanol proof and stainless braid can just hide perished hose so best avoided (IMHO)

They use stainless braided in motorsport even when they are using ethanol as the fuel.

Don't get confused by the stories of standard cotton braided fuel hose perishing.

Buy the right stuff and it is much safer than rubber type hose. (from experience)

Take a look at this shop on EBay, like I said not cheap but rated for methanol and nitromethane.

Pirtek for all my fuel lines from the tank outlet to the carbs. Can't go wrong in y opinion. Not Cheep but you get what you pay for.

You will know if you have the correct replacement. The hose will be marked accordingly. As the lads say previously pay a few bob more for the rated stuff.

As per Flags comments. Mine are stainless braided teflon, mine you they can be awkward to make up. AN fittings all round. Try Torques UK, or Speedflow. As the guys say, not cheap .

I think the correct hose for ethanol is labelled "R9" ?

I went one further and use bio-fuel hose which is almost 100% ethonol proof (if you buy the better stuff as every one else has said).

Even R9 can suffer over time as they keep uping the % of ethenol in fuel.

The key is don't buy cheap from an unknown supplier. One thisng not to skimp on

Chad👍 R9 will still break down

R9 is high pressure hose, there is also R14 which is the low pressure equivalent.

I'm currently using R9 from tank to chassis and chassis to fuel filter attached to fan housing.  Am switching to landlines across the engine so there is no chance of breakdown of pipe

Hey Buddy,

I've used a company called Think Automotive, they are specialists in Oil cooling systems and all aspects of vehicle plumbing for the daily drive or the motorsport industry.

They have made all my plumbing from Brake hoses, hydraulic pedal lines and fuel line. They have a huge range of fittings to suit as well.

Best of all, they will make it all for you onsite and made to measure.

However as mentioned above by others these are not cheap parts. My fuel line from bulkhead to rear fork with all fittings came to just over £50.

LUDICRUZ , good call. Never seen this site. Mainly used Speedflow direct. Fay Fischer (owner) is ver knowledgable, her background is drag racing. Mind you, as you say, not cheap.
