I am testing the fuel tanks using the manometer method. I've had about a 3"/10 hr leak. I used soapy water to find a small leak around where I duct taped the fuel filler cap. I'd really like to seal it up so I can make sure I don't have a really small leak somewhere else. I haven't seen anything with the soapy water but I'd sleep so much better at night with a solid water level.
Long story short anyone have a good way to make the fuel filler cap air tight so I can be sure the tank doesn't have a small leak somewhere else.
Thanks
