Hello all . First post on this forum but i've been a viewer for several months now and have found it to be very informative . Sorry that my first post is a question rather than advice . Been running my e300td on vegetable oil for a couple of weeks now after doing some research and believing that apparantly my car needs no modifications to run on 100% svo . Been running great , smoother and quieter than before , and at 43p a litre i was well chuffed . Until yesterday that is . Appears that i've done the seals on the fuel pump and am faced with a bill for up to £1100 . This was based on a quote from a diesel injection specialist . Does anybody know if this seems reasonable or am i being ripped off ? When i spoke to the mb dealer parts dept they were talking about 25p each for the seals but needed to know exactly which ones had gone and to wait until i'd stripped the pump down before ordering them . Has anybody any experience of having this done and cost etc ?
