1989 fleetwood Econoline 350 fuel leak

Any auto supply will have the fuel filters, and maybe the clips in their HELP lineup. HELP is a display of little oddball pieces like clips for door handles, door trim, lamp sockets, up to a square yard of facings somewhere in the shelves. Our local Advance has filters and the HELP stuff, I just don't know if there's clips. A shop might have some used ones laying around. They can be removed carefully and the barbs not damaged, but you can use with zero barb left if you secure them from getting "unplugged."
