Bear in mind that rubber fuel hose is double layered with reinforcing in between. Having contacted Gates to clarify their hose is E safe I was astounded to find the outer layer disintegrating when exposed to a leaking fitting. Going back to Gates and asking why ? was informed that only the inner layer was E compatible !!!!!!!!
Bonkers or what !

Interesting! So how on earth are you meant to monitor the condition of that??

In the case of the leak, it was behind an undertray, so hidden from view.
So if using rubber hose it would be advisable to have all the joins accessible to view.

The answer is Teflon lined braided with pre formed end fittings.

I have used Viper's offering, amongst others:

Out of interest, why would you require pre-formed fittings, Mark? I usually make up my own hoses.

Sorry, perhaps not the best terminology.
As you have linked, this type, not the mickey mouse shrouded jubilee clips.
