see if you can still get a fuel system from Morgan Custom before he runs out of stock.
Or just get the uprated fuel kit from M3Wservices in Swindon - still uses new 'standard' correct type fuel pipe but also has a proper fuel filter and regulator.
Lot cheaper and works well.
That is of course if you need it as I still think its more likely an oil leak/wet sumping - have you carried out your checks yet?
