I was just over at Earls and asked about why my braided fuel lines had lost flexibility. Answer was if you are using PULP then this will happen as the additive used to up the Octane is not compatable with the liner. Next thing is they will leak.
Apparently this is in the smalll print in the catalogue but not displayed any where in the shop. I suppose its a buyer beware situation but after spending over a $1k on neat looking fittings and braided line that are now totally useless I am not a happy bunny and mightily peeded off with Earls.
Earls suggested the teflon lined but added the disclaimer they wouldn't guarantee them in a EFI situation. Seems odd as this is similar to brake fittings which run higher presure.
So its back to the drawing board
