Air compressors

Hi gang
my small compressor is on its way out its really getting slow at filling its tank I have a spare 150 ltr tank here but could do with a pump would a pump from a 7.5 ton ford 0813 or iveco 75e15 do the job or i could use two i intend to use a 6.5 hp petrol engine to drive it.

let me know what you think about the compressor
