Where do you hook up the oil metering pump tubes on a weber 48DCOE? Also where do you get the right kind of linkages to make it fit?

 

Have you considered running premix? If you'd rather keep the metering pump then you'll need to drill and tap the manifold to accept some suitable brass fittings.

As for the linkage, I don't know where you can buy these from but you could possibly fabricate your own... which is what I did. I used parts from an old Nikki carb I had lying around and some aluminium.

 

48dcoe or a 48ida... ida is preffered.
Instead of worrying about linkages you could use a cable tie to permanently hold the metering pump half open. revhed's premix suggestion is good as you can run a oil that is specifically designed to be burnt.
