The Edelbrock mechanical fuel pump block-off plate (#4021) is a billet aluminum plate for big-block Chevy applications, machined with countersunk bolt holes for a clean installation. It provides a durable, finished method to seal the mechanical pump location when converting to alternate fuel systems. While intended for big-block Chevy installations, the plate may also fit other applications listed by Edelbrock where a billet, countersunk block-off solution is required.
