What hoses go to my fuel pump?

Hi all! I just recently purchased a new fuel pump (see
Amazon Amazon
). I was looking at some pictures I had on my phone to ensure it would work. I am a bit confused as to what hoses acually go to my pump? I noticed one hose (i think my middle hose) was cut and plugged off. What hose is this? ill post the pics I have!
Thanks.

Re: What hoses go to my fuel pump?

So facing the engine bay standing in front of the car, follow one of the hoses from the pump, to the left between the exhaust manifolds and the inner wheel arch. You should see 2 steel lines, one larger one one smaller one. The large one is FUEL SUPPLY (From the tank) the skinny one is FUEL RETURN (back to the tank) which carts excess fuel back to the tank.

The remaining hose on your fuel pump will will travel upwards to your carb, throttle body etc.

The only one that would make any sense being blocked off at any point would be the skinny return hose that takes fuel back to the tank.

Hope that helps
