at least with the first generation of Walbro pumps, you also have to put in a check valve on the supply line. See the Townsand site for the best way to do this. By 92, the check valve may have been standard, but it doesn't hurt to look. Also, the first generation of return line check valves on the Walbro's were faulty, so your return line may not be generating enough pressure to work the pick-up valve at the bottom of the pump housing.
Good luck,
ETS
