NOTE: This system comes standard with push-lock fuel hose which CAN weep a bit of fuel smell. We have used this hose in several of our shop cars with both gasoline and E85 with excellent results and no fuel smell, but some customer have noticed a smell and Fragola has acknowledged this. If you decide to purchase this kit with the standard hose Lethal Performance will not be liable for claims of fuel smell after installation. To avoid any chances of this smell, it is recommend top purchase the line upgrade kit that uses PTFE fuel hose elsewhere in this section.
