My 2005 Ducato 2.3JTD has just sprung a leak from the fuel filter housing: it appears to be a hairline crack at the point where the lower bowl is flared for the pipe entry.

Two questions, really:

First, how many other Fiat/Alfa vehicles (or any other makes?) use the same components? (marked UFI Filters 23.55.143.20) This might improve my chances of finding a like-for-like replacement on a vehicle being broken for spares.

Second, I notice that the housing is fitted with two sensors: a lower one (white conector) which I assume is a water sensor, and an upper one (orange connector) which detects what??? Question here is, if I was to throw away the standard filter equipment and fit generic Bosch housing + filter, would the sensors being disconnected/abandoned upset the engine management system?
