1.8 carb to 1.8 gti

Iv got a 1.8carb engine in my clipper n iv got an engine out of a golf gti cabs.
I'm just wondering is there much work needed to change them over? 
Both cars are H reg 
Iv got 
Engine 
Loom 
Metering head 
Fuel pipes 
Manifold 

have you got the rear wiring loom plus the fuel pump, accumulator, lift pump and under car reservoir?

iv got all those parts apart from the fuel pump
just got to get my hands on one

fuel pump is same as a normal mk1 gti one so shouldnt be too hard to locate, try to get genuine bosch if possible tho
