Portable Gas Tank/Fuel Line

I am near having my jonboat restoration project completed and need to buy a portable fuel tank, fuel line bulb, etc… I have never had to buy any of these items, anything I should know, anything I should stay away from? Best place to get?

I am running a 15 hp motor on a 14’ boat so am thinking about a 3 gallon tank to cut down on weight. I would imagine a 15 hp would get pretty good mileage. Any reason I should go with a 6 gallon tank?

Just looking for some constructive thoughts or input.

Thanks

3gal is fine. You can do a lot of fishing before the 15 uses it up as long as you don’t make a lot of long runs to and from. I use to have a 3 for fishing and a 6 was for shrimping. Had a couple spots that were 10-12 miles from landing plus you never cut the engine off. Got kind of close a couple times with the 3gal then.
