Are these Gasoline resistant plastic fittings?

[Mark42]

Looking at Nylon, I'm fairly sure Nylon is used with gasoline in many small engine applications.

What about polypropylene? I see these barbed fittings used in the underground sprinkler systems. Will they hold up to gasoline exposure?

I don't see a problem as they make gas tanks of polypropylene...

I redid the fuel pump on my Merc 35 earlier this season.
The rubber plugs which hold the diagrams in place were replaced with plastic (I assume nylon ?). This was a Sierra Kit.
