If the only issue is at the return connection up front at your tunnel line I can help.
I can make up a Front Return
Hose for you as the lower one in this photo.....
The most common need is for the Hi Pressure Feed from the Pump, but I offer both if needed. You will need to cut back the crimp sleeve and clamp this repair hose in place.
Please email me for info.
