Does siphon pump to empty reservoir need to have food safe plastic?

[The123321]

I know this may be a weird question but I want to get a small hand powered siphon pump to empty a reservoir. I found some $10 hand siphon pumps on amazon that is listed to use to transfer gas or water from aquariums but it says it not for drinking water. Does the plastic in the pump need to be food safe if you put it in the water in your reservoir to empty it when cleaning the reservoir on there?

If you're talking about the ones they sell near kerosene heaters in department and hardware stores, the ones with the little squeeze bulb thing to get the flow started, I used to use them for emptying out DWC reservoirs and never noticed a problem from doing so.
