fuel line?

Postby dickcub50 » Mon Jan 14, 2013 7:28 pm

What is the correct threads for the carb. inlet and the
fuel sediment bowl? I picked up several items and PO
must have used anything close. Hope to salvage some
items. Not just for parts.
Can a heilcoil be inserted?

1/2-20 is the correct size, but some people will thread in a fitting that is pipe thread and booger them up. They can be drilled and helicoiled.

There are two ways to get enough Cubs. One is to continue to accumulate more and more. The other is to desire less.

1/2-20 is the correct size. Bill, you must be thinking about implement holes. :D

Yes, I pulled it up and read across the wrong line. So much for that new eye. :oops:

I better edit my post so nobody reads my reply and goes no farther.

Thanks for the info,now I can try to salvage some items.
Some are parts only. When you get a box unseen, you
hope for the best.

There is a pilot guide that was designed by Rick Prentice to center and guide an end drill prior to tapping for a helicoil. Without one you may have a hard time getting a straight hole. If you were in the midwest or east, I'm sure you could borrow one, or have the helicoil done at a Cubfest. The fitting that stripped the threads was likely 1/4" NPT. Edelmann makes this fitting (168540) which can be used if you aren't concerned about correctness. Image (photo from Plews-Edelmann website)

For the line itself, standard 5/16" brake line works and they come with fittings. But you will need a couple of ferrules.

Lots of good info around, try a search. (it's a 'popular' topic).

When seating the new ferrules use a different fitting and not the carb inlet. Those carb threads seem the be soft and a lot of them are stripped out that way.
