It depends, some of the XR's/injected Orions had a different sized fitting
with a smaller banjo on the end of the fuel pipe. You can still connect the larger RS banjo to the pump but almost invariably there will be a small air
leak, which will mean it's a bitch to start and even when you do get it going
the ingress of air into the system means that 30 mins after you turn it off
re starting is VERY difficult. With any luck you'll be OK/if the outside diameter
of your pump output is 11.75 mm you're fine if it's smaller welcome to my club.........
