Hi Alan
The hoses were from Earl's and they are AN10 with the correct fittings that must be used with this type of hose as supplied by Earl's.
Under no circumstances can Teflon lined hoses be used with standard hose clamps.
When I first used new fuel hose there was no problem, but after a period of time the leaching of fuel through the hose began an progressively became worse till I could not stand to be in the car for any period of time which prompted the change to Teflon lined hose.
