Brandon, crawl underneath and look up at the tank, I've been wondering the same thing, but no SD here
swapping tank strainers can be done without emptying the tank but you might get a bath (like I did) if its your first time. as a suggestion tie some rags around your wrists to keep fuel from running down your arms. Also get a new hose and screw it into the new strainer so you can clamp the hose off and screw the whole thing into the tank without leaking too much out.
If you have a lot of gunk in the tank you might want to remove the tank to clean it out fully.
