hi shawnusa, two things come to mind, 1 drill oversizes holes and use goop or any clear poly caulk, goop works great cause it sticks to almost anything. #2depends on what size fuel line, but, drill holes to snug fit a short section of brass tubing,epoxy perm. in place, make sure there's enough tubing to attach line's to on either side,fuel line will have no contact with fire wall
