Also managed to find someone (which was where i got my fan replacement from) uel problem he said that I shouldn't have it centralised as this is making the fuel travel further and not atomising properly ie going into droplets he said I sould split and have on each side, is this right? I am asuming with 2 air filters one on each side? He said this way I should be able to get at least 30 to the gallon, set up the old way. sorry to keep asking but you have given me such valuable advice so far I value your advice/opinion.
