Minispares sell 2 different types:
1) FUEL PUMP MECHANICAL TYPE FOR 1990 ON 1275cc VERSIONS (AZX1817)

2) FUEL PUMP MECHANICAL UP TO 1989 (AZX1818)
http://www.minispare....aspx?pid=34648
I need a new one for my 1275 mayfair (1993) and the one i need is AZX1817. However this has been out of stock for since the end of feb and minispares have told me they don't know when they will be getting any in! HELPFUL!!!

Minisport and such sell one type of pump guess this is of the universal variety. In this case would it be possible to use AZX1818 on my engine or are there major differences between the two?
Cheers
