Sorry Cameron,
Misread your query in haste
Pretty sure my inlet and outlet lines are aluminium (no car to check - sorry)
My pump is an NC Fairlane (V8) and it fits okay.
With the EB pump is it off a 6 cylinder?
I was told by Ford that all the V8 pumps are the same and similarly the 6 cylinder one's are different.
On my old pump the plastic take off is 8.5m o/d with an internal dia of 5mm.
Does that help????
