Should be 1/4” NPT.

 

Might be that the port is 1/4" NPT?

In which case I need to find a barb with a 1/4" thread and a 3/8" barb?

 

The thread size should be 1/4” NPT, and you can get whatever hose barb size on the other end.

 

Thanks. Just looking up the catalogue now.

 

If you have an Ace, True Value, or Do it Best Hardware near you, go up there, they have a huge selection.

 

Just ordered.

We're in a lockdown with 5km radius travel limits (and only for essential purposes), so did it online. (Melbourne, Victoria, Australia.)

Thanks.

 

1/4 NPT Similar to Carter and Edelbrock carbs.

 

Wow... you can't get beyond 3 mi from home, even for an essential purpose??

 

That’s pretty much it. Also there is a 9pm curfew.

The only reasons to leave home are for medical, essential shopping, essential jobs, one hour exercise (with just one other household member). Masks and 1.5m distancing apply.

Not so bad given it’s been winter, and as we get our vaccination rates higher the restrictions will be easing.

Australia managed to have zero cases for many months until Delta came along. Now we have one state where it got away a fair bit; one state (where I am) where it got away a little, but is being kept low/steady; and all other states have no cases.

 

If they would do that here, maybe they could get this under control.

 

Just got these parts in – correct thread size and all!

Question: I want the elbow fitting to rest either at a 9 or 3 o'clock position so as to take the secondary attachments (and hoses) out a side. Is it ok to use teflon tape to adjust the turns of the fitting to rest firm at this position? (I know it is bad to use tape on the fuel lines etc., but that's all before the carb.) Can see that the PO used a bit of tape even on the carb base plate plug that is already there – although not sure why that would have been needed on a tapered thread?

 

Should be fine on a tapered NPT pipe thread. Once it gets snug, you can line it up as needed, as long as it does not take an entire round to get where you want to be. You have judge that as tightening.

 

That’s pretty much my question. If these brass parts find snug at 12 o’clock surely they won’t go another 90 degrees to find final position, so do I use tape? Or am I underestimating the material?

 

On a pipe thread, and especially if brass as most hose barb fittings are, you might get 1/2 turn after starting to get snug, anymore, it may snap.

 

Gotcha. Thanks a bunch. 1/2 a turn is the max I would need. Will get this sorted early next week.

 

Hope all goes well with the assembly!

 

Yes, you can use pipe teflon tape to assist in fitting location. Best for vacuum ports. With tolerance variations, if you buy several fittings, there is a good chance you find the angle you desire. Like indexing spark plugs..buy 12, to index 8.
