Fabricated a bracket to secure the fuel pressure regulator to the airbox and carburetor. Riveted the bracket to the end of the airbox. Used a cable clamp to secure the pressure regulator fitting to the bracket. Turned a 8mm long spacer from 3/4" aluminum round stock to correctly space the regulator clamp from the bracket. Fastened the clamp to the bracket with a AN3-10A bolt.
