I see a couple other things that need to be changed there.
The line coming from the fuel head just to the right of the main fuel supply inlet is not high pressure fuel injection line, it is German vacuum line or old German carburator fuel line and it's fastened to the banjo fitting with a cheap hose clamp.
It will not tolerate the 95-100 psi fuel system pressure that is inside it for long, it will pop or split inside under the fabric and leak gas.. and some of the fabric covering over the rubber line looks to be frayed just below the hose clamp.

That line goes to the lambda frequency valve that bleeds fuel off the lower differential valves (orificed system pressure in the fuel head) and returns it to the fuel tank.

Also there is a loop of similar line laying on top of the throttle linkage going to the throttle body. That line looks a little newer or recently installed and every time you move the gas peddle that linkage rod is rubbing on that hose and will rub through it eventually.
