E 250 5.4L V8 - What type of hoses are these?
 

I have P0442 small leak code on and was looking at the hoses for leak. Does anyone know what these arrowed hoses in the pics are? they look almost damaged and was thinking of replacing them but don't know what they are called? One of the is coming from canister I guess? Can I just buy any similar hose from out store and replace them or these are specific OEM parts?

Usually an auto supply store will have the various size hoses to replace defective hoses.
You should get "Fuel line hose" which should be more resistant to any possible gasoline vapors You can use fuel line hose to replace vacuum hose, but you cannot use vacuum hose to replace fuel line hose.Just take a sample into the store with you and they should be able to supply whatever you need..

Thanks!

Those lines look to be with the evaporative system going to the tank for the vent. That isn't reinforced fuel line and you don't need reinforced fuel line but hose line suitable for the evap system.

Not all fuel line is reinforced.
The difference between regular rubber vacuum hose and fuel line hose is regular hose if exposed to gasoline will get soft and spongy and mushy. Fuel line hose will stand up to gasoline vapor exposure and not change..

Yes, there's little if any pressure in that hose, therefore reinforced fuel line is way overkill since it is not involved in actual fuel delivery.Thin walled fuel vapor hose would be suitable for his application.
