Found another vacuum pump

 So my brother came through for me and sent me a spare vacuum pump he had. (He also sent me the old o ring it had.) His pump looks the same as my old one except for one minor difference. The tube for the oil return line bends downwards and the one on my old one came straight out. This minor difference made it very difficult to attach the oil return hose, I ended up cutting the hose in an attempt to get it on the pump better but it didn't work out.

In order to replace the hose I had to remove the banjo fitting's barbed end from the crimp. I had to carefully use a grinder to get the crimp off. This was a bit tricky but it worked out.

However Even after replacing the hose, the angle was still too awkward to make it work.
