Has anyone used 100% biofuel in a Ducato 2.3JTD? Ours is 2003 model. It runs well with up to 20 to 30% fresh vegetable oil added but I now have access to good quality tested, "proper" Biodiesel (Methyl Ester).I cannot identify the fuel pump and am a bit concerned about it possibly being a Lucas pump which some reckon on being problematic on 100% Biodiesel. Any help welcomed please..................
