The purpose of the gasoline strainer is to prevent any water or foreign matter from being carried into the carburetor, and this device should be used on every engine if the owner wishes to be free from carburetor troubles.
(112) Installing Gasoline Carburetors.
(1) Use brass or copper pipe from the tank to carburetor if possible to avoid trouble from dirt and flakes of rust.
(2) When installing a gasoline tank be sure that the bottom of the tank is at least six inches above the carburetor to insure a good flow.
(3) The tank should be provided with an air vent hole, or the gasoline will not flow because of the vacuum in the top of the tank.
(4) All tanks should be provided with a drain cock at the lowest point so that water and dirt may be easily removed.
(5) Clean out the tank thoroughly before filling with gasoline to avoid clogged carburetors.
(6) Pipes from the tank to carburetor should never be placed near exhaust pipes or hot surfaces for the gasoline vapor may prevent the feeding of gasoline.
(7) Clean out pipes before using.
(8) If common threaded pipe joints are used on the gasoline piping, use common soap in place of red lead.
