Fuel accumulator

Hi, does anyone know of any breaker where I can get a fuel accumulator? Many thanks.

I have one on my 83 gti, I have seen the car start and tick over, although I haven't run it in the 10 months I have owned the car. I have removed the engine to fit something different, hence I don't need the accumulator any more. ( just to confirm we are talking about the item under the car near the fuel pump, my old brain gets muddled up these days) Actually I had a few minutes to spare so I removed it, still full of petrol which was a good sign but I could not undo the rusty hoses, afraid I would shear the connectors of completely if I exerted any more pressure, so assume its no go..
