Wellcome to iboats Dell.VRO's came out in 84' on the larger engines. What's the model number of yours? We can give you the year from that.If you bought a used VRO pump from the 80's, probably not the best thing in the world to do. Can you give us a description of the harness on it....how many wires is in it? What color is the fuel outlet on top of the pump? Gray, brown or black?
When in doubt...use the manual
