    Hi everyone,

    two of my gaskets that connect the fuel supply to the carburators on my Daytona are not 100% sealing anymore. When the engine is running after a couple of seconds one can see that these two gaskets change their colour and become darker than the other ones. The part I‘m talking about is part number 17 on the attached part catalouge.

    Unfortunately there is no part number shown on the part catalouge. Does any one know where I can get these gaskets and which part number or name I should be looking for?

    Best wishes,
    Ferdinand

    The Ferrari part number for these red fiber washers is 93353. They are the same ones used on the fuel pump; this is where you can find the part number. If you don't want to buy new ones, put Hylomar on the olds ones and this should stop the leak.

    Amazon sells a red fiber washer kit. I believe the ID of the Ferrari washer is 12 mm for all the banjo fittings. If concours correctness is not an issue, many experts recommend replacing the fiber washers with copper crush washers. The banjo bolts need to be periodically tightened to prevent leaks. Do not over tighten the bolts, just make sure they are snug.
