You need to specify whether or not you have a standard fuel pump or an 044 motorsport pump, or other type.

The standard pump only had a thread on the outlet side. The 044 motorsport pump has a thread on both ends, and they are different sizes.

My standard pump on a 2wd cossie has a non threaded inlet. I think this is the same for a 4wd.

As stated above, the standard pump's inlet uses a push on type hose fitting which fits approximately 16mm ID (internal diameter) hose and uses a hose clip to hold it on.

I would suggest replacing any original equipment flexible fuel hoses on a Cossie as old ones tend to perish and can leak posing a fire hazard.

Especially true on the 2wd Cossies for the fuel line between the fuel rail and the fuel pressure regulator.
