Brand new Fuel pump for the USA build Pontiac V8.. using 347, 372, 389 & some 421.
Check the picture up against whatever you may have.. . . Note too.. some Australian assembled 57 & 58 Pontiac's used a vacuum line OFF the fuel pump for the windscreen wipers... THIS IS NOT that type.. but rather the USA Built 57 & 58.. and up to 65 mostly big car series.. that had then electric wiper motors.
