You might want to refresh our memory on your project and your goals to give the best answer, however I'll give a general response - there are a couple brands of electric water pumps on the market for FE's, like the Meziere, however they don't have anywhere to bolt on the original style FE alternator brackets or power steering pump bracket and you will have to fabricate something yourself, Jay's water pump adapters have versions that allow you to use an original Ford bracket. Otherwise, no you don't need an adapter for the other brand pumps just to bolt them to a FE. One other plus with Jay's adapters is they allow the use of a higher flow 55 gph CVR pump, which can be helpful if you are using this on the street, the other brands of FE electric water pumps are lower flow, although not generally an issue if just used for drag racing.
