    2003 MERCURY 3.0 LITER 250XS OPTIMAX Black line

    Hello,
    Trying to find part number for black line. Looks to be 1/4" in size.Found one with a small crack probably due to age.Plan on replacing them all.
    Need the small custom tie wraps and tool.
    Can you get hose in a roll?

    I searched for that p/n 8M6003283 and it shows $197.00. Is that a kit with all the hose fuel supply lines? Can you only buy just a few hoses? Was going to replace all since one was cracked but wow $197.00.

    Perhaps a good idea to mark up (or POINT TO) a specific, SINGLE hose. Your above pictures contain BOTH oil lines AND a Fuel Line (the fuel line is in a protective sleeve).

    NEITHER is available in a "roll".

    See Rhonda's post (pinned at the top of the Forum)- the entire Mercury Parts Catalog is on our website (including the ability to order direct with a BBC discount).

    Sorry for the confusion. The hose I wanted is like the one in picture going to the white filter (oil Line). Tried looking at Mercury Parts Catalog from Rhonda's post. Will try again.
    Thanks

    Don,
    I added more pics. I Tried looking at Mercury Parts Catalog from Rhonda's post but unable to find line. Probably order a few. Not sure where the leak is coming from.Going to remove all the lower cowlings clean up and start motor is see if I can tell where it's leaking. When I have the LU trimmed down all the way in shop and sets for days I noticed oil running down the seam of LU cowling at the back above prop.Not a lot just a drip or two but bugs me. I will post more pics after taking cowlings off.
    Thanks Tony

    JOE54,
    I found the 8m0054152 bulk 39" on European Marine website. Going to order some.Does it take a special tie wrap and tie wrap tool? I didn't see it on European Marine catalog.
    Thanks for your help.

    Doubtful... if it does help it will be very short-lived. Best bet is to simply replace.
