The manual will come with your install instructions, if you ask for it. For the LC200's the only real option is how long you want the pump to run when it hit's the empty mark. If you use the included pump you can hear it change sound when it's hits actual empty, vs sensor says empty. The pump when pumping air starts to sound like wood pecker. Most people leave it as is set from factory, If you don't hear that sound you know you still have some reserve fuel and can hit the button for it to pump for a couple more minutes. I'm not sure how to attach a PDF file to a post.
I suspect this weekend and next week (at least for this area) likely see some fuel shortages.
