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.

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.
