Tank out! found the leak,corroded feed pipe.
As a quick fix, I'll repair with a high pressure rubber fuel hose until I come across a decent fuel pump at the breakers and by the looks of it a decent fuel tank which i know are hard to come by,in the mean time i will clean and paint this one for now.
I also made some new tank strap securing bolts/hangers, the originals couldn't be used again they were scrap.
