Default My Twin Walbro 255 Fuel Pump Set up. Pictures and Info

I was tossing around the idea of either one 310 fuel pump or 2 walbro 255 fuel pumps. With alot of talking and researching i decided to go with two fuel pumps. Its cheaper, flows more, and is something i wanted to see if i could do. I talked with a few supra tuners and they told me how to do it. Basically this is it. I drilled a hold for the fuel feed and welded a tube to a fitting. Then sandwiched the fitting with a special washer, a nut, and some chemical proof silicon. I ran the wires through another hole and used silicon on both sides to seal it. The power Wires are relayed and hardwired to the battery. Each fuel pump is fused with a 20 amp fuse. The relay trigger switch is run off ignition with a switch inline to kill the power if need be. This set up will be pushing an extremely large amount of fuel. I have switch the fuel return line with the fuel feed line. Now the fuel returns to the tank using the larger feed line. The fuel pressure will be increase alot due to the small return line, but i can fine tune it with the fuel pressure regulator. I am sure some of you will have doubts, but i just tested it and it works.
