If your Buell motorcycle's fuel system needs some attention, this strainer set might be exactly what you're looking for! Designed as an exact-fit replacement for Buell Firebolt XB12R/XB9R, Lightning X1, Thunderbolt S3, Ulysses XB12, and XB9SX/XB9/XB9S models from 1997-2007. These in-tank strainers work with modern ethanol-blended fuels, including E85, which is great because ethanol can really mess with older fuel system components. The quality meets or exceeds OEM specifications for fit, form, and function, so you know they'll work properly in your motorcycle. Perfect for bikes that aren't ridden daily or have been sitting for a while - those are exactly the conditions where fuel strainers tend to get clogged or degraded. Just a heads up - this is an international product, so the packaging and instructions might be different from what you're used to, but the parts themselves are built to the right specifications. If you're experiencing fuel delivery issues, rough running, or just doing preventative maintenance on an older Buell, replacing these strainers can make a big difference in performance and reliability. Much cheaper than replacing the entire fuel pump assembly!
