The Banjo connection at the pump should look like this from the factory and when made up on the bench with the proper crimp tools..........
If made up on the car, the hose should have a Oetiker clamp like this........
It appears they may have cut the old hose off at the original 10mm Banjo and clamped the new 12mm Banjo in place.
Check the hose condition carefully, it may be the original and close to 30 yrs old like these...........
This is what I make up for a Pump to Tunnel replacement...........
It uses fittings at the tunnel instead of a permanent crimp so a new tunnel tube is necessary as well.
