Jack, the grommet is available from GoWesty, and I think from Bus Depot.  GoWesty includes it as a part of the fuel line replacement kit, also.  It is pretty simple.  You just use a length of fuel hose long enough to reach to the proper place on the fuel distribution system on the engine.  Fit the grommet into the firewall opening where the current plastic fitting is, and pass the hose through it, attaching it at both ends as appropriate, with good clamps.  I think I did buy mine from Bus Depot, but it has been a while, and I replaced all the fuel hoses at the same time, so it may have come as part of the kit.
