Hi might I sugest you you find an older macanic and just ask him what they are for.. I find mostly they dont mind telling you. Or if it were me id call a fiat main dealer and ask one of there macanics.. whats the harm in telling you. Photos are good to determin what make of pump I have a 1.9 it has a bosch pump..
