Would anyone know or suggest what I can use as a replacement for the plastic tubing that links the actual metal pump to the pump housing? According to realOEM it doesn't have a part number so unlikely I can source the same item.

I'm thinking of trying to use some actual fuel line, I believe it's reinforced anyway, or something similar. It simply pushes up onto hose-barbs on the housing and pump but is clamped onto the pump end with a compression clamp similar to a jubilee. Can fuel line be gotten handy enough? I'll need about 18-20 centimetres I reckon.

Is there anything else I can get? It's the part 'looping' roughly above centre in Part # 1 here:
