Disconnected mine years ago, 40 mariner. Got a measure from BPS that gives you several fragile to chose from and by the gallons of gas. Keep it in back next to tank with oil. Fill tank, if it takes 3 gal then add to line for 3 gal at 50 to 1 ratio and add to tank. Will be mixed by the time you get to water. Some one said you could find them at Wally world to.
