Fuel bottle/Fuel tank idea
I got the idea for this from Silverbear in another thread but he used copper fittings and altered it a bit. This is a stainless steel water bottle purchased at Ross for 5 dollars. You can also get these at Target and other stores. Then I bought the brass parts at Lowe's. There are two parts. One is a male 3/4" pipe thread to 3/4" garden hose male adapter. The second part is a hose cap. The reason for changing out the plastic cap is so it will be fuel proof.
This will work well for a fuel bottle to carry extra fuel with you.
