That fuel pump nose adapter from Hughes is an abortion... I had to re-engineer it when they sent me the wrong camshaft with that band-aid... I wanted the correct cam with the nose incorporated in it... No, they send me the magnum cam without the nose and add another $30 for that adapter kit to pump up their sale....
I modified a key way to replace that cheap *** chunk of aluminum that is supposed to clock the fuel pump eccentric...
