I haven't found any photos of a manometer hooked up to the fuel tank to measure the 1 psi needed to check for leaks. So, here is how I set it up:

Hooked a bicycle pump up to the Shrader valve at the yellow arrow. Pumped it until the column of red water in the Tygon tubing (thanks Larry) reached a differential of 30" (that's about 1 psi up here in Colorado. It will be different if your elevation is different, naturally).
Leaks found with bubble liquid obtained in the aircraft aisle at a local toy store. My leaks were at the ground screw holding the float mechanism to the side of the tank. A little sealant on the threads and the washer should solve issue. I'll find out tomorrow.
