Metal fuel line question

[MattC]

If you know the threads, Mcmaster might have the fitting. If not, you should be able to find a similar solution on Mcmaster.

Sounds like you're on the right path.

Well I'm getting an education on compression and flare fittings for sure. Cant find a direct match on line. When u look into the nut on these, it's square bottomed, so I'm going to the hardware store and prob home depot plumbing section and compare. I could substitute any which way but be nice to try an get to the bottom of what IH used originally.

I doubt if IH had anything to do with the carbs and lines as the engines were delivered (probably) with this equipment already installed Plus the compression nuts are listed in the parts look up as #KH-220786 (NLA) surprise, surprise!!
Also listed is the sleeve for $5.89 still available part #KH-220547-s
$5. 89 for 3/8" long piece of 1/4" fuel line....Hmmmm

very cool. I think i can get one more nut, a hardware store compression elbow, and cut a couple pieces of 1/4 line for the rubber inserts plus some metal brake line, which I think would be 1/4" ? I'll measure for that...

thanks for the help. where did u find these part numbers?

UPDATE found a drop down that has 70 & 100 100 70 go figure!

OK I want to love it but it starts with asking a model number. I have a Model 100, I tried every variation on that and nothing... what model number can I use to look up parts? My tractor is 1964 100...

Try this link instead, I guess the one above is for all the modern crap, sorry bout that!!
This one will take you, under the garden tractor drop down, to pretty much all the Cubs folks on here are concerned with

Select garden tractor and go from there.

just click on the dropdown line for the 100 or whatever other model you are looking for.

My son bought his original in pieces at an auction, after we sand blasted it, had it all painted up by a high school body shop instructor, and put it together, my son put gas in it for the 1st time and unknowingly to me, reused the original rubber grommets. We woke up and went out to the garage to find a puddle on the ground and our brand new iron gard paint peeled off in a streak about 2"wide directly below the metal fuel line. This paint had been allowed to cure for a couple of years in the attic as he had sort of forgotten about it before reassembly.
I like the idea of metal fuel line over rubber any day of the week, but by all means replace those rubber seals if you ever need to take them apart.
I dunno about using just any old grommets from the hardware store, there are many different kinds of rubber, some more fuel resistant than others

thanks fin and dodge. well I got a 1/8" NPT x 1/4" compression fitting at the hardware store to my amazement. Got a short piece of 1/4" brake line. had to drill the CC fuel bowl fitting nut hole it was prob for 3/16". Got some 3/16" and 1/4" fuel line and cut little donuts with a razor blade. Only the 3/16 would stuff into the compression nuts. When the 3/16" was in there obviously the 1/4" brake line would not go in so I drilled the rubber which left a uneven surface but I figure my Permatex #3 would deal with that. The brake line goes in pretty tight and of course can sock down that compression nut and squeeze the rubber tightly. Lotta aggravation to replicate the original method! Woulda liked to just use flare fittings (I have 45 degree a flare tool set)
and be done with it but Dale said that might crack to his estimation because he thinks the rubber allows for vibration but now we have a report of a leak with the rubber go figure!


LOL this is kinda fun. gettin to know my tractor...

by the way does that carb look correct for this 100?
