Fuel Inlet Fitting?
 

I’m new to Stromberg Carburetors and for the life of me cannot figure what thread the inlet is.

Re: Fuel Inlet Fitting?
 

Many years ago parts stores had a Stromberg designated fitting just for this. It is quite possible that Michael Driskell at 3rd Gen has them. If you live near an old NAPA they might have the fitting also. I have a few and that is where I found them.

I just looked on 3rd Gen's site and he does have them in stock.

Re: Fuel Inlet Fitting?
 

Used to be able to get them at the parts store; maybe some are left somewhere.

Here is an old one. The ferrule is a sleeve that is fairly tight in the nut

Re: Fuel Inlet Fitting?
 

How does the fuel line connect to it?
If anyone has one to sell please let me know, I think that my whole project is going to come to a stop due to my inability to get fuel into the carb.

Re: Fuel Inlet Fitting?
 

I need to see what the other end of it looks like so I might possibly figure out how it connects to the fuel line.
After working on an engine swap for 2 months I’m nearing completion and now I discover that I don’t have a way to get fuel to it.

Re: Fuel Inlet Fitting?
 

FYI

When building or repairing a fuel line, use a good quality 1/4" ferrule; the ones from the plumbing department in a big box store might not be up to the task.

Unless someone previously wailed on them, the nuts can usually be reused.

Re: Fuel Inlet Fitting?
 

The ferrule of the original fitting made especially for the use on the Stromberg is not just a short ferrule like all suppliers now sell, IMHO. The ferrule is longer and feeds back into the fitting like a sleeve. It is not like a separate nut and ferrule. With the proper fitting you can put the fitting/ferrule on the carburetor and then push the fuel line from the pump until it bottoms in the carburetor and then tighten the nut. The same fitting works on the pump if memory is serving me today. LOL

Re: Fuel Inlet Fitting?
 

The fitting into the carb should be the same as the fuel pump outlet. In my opinion the nut with the captive ferrule is not as good as the ones with a separate ferrule. I have used a nut that did have a captive ferrule with a separate ferrule but a nut designed for a separate ferrule is preferable. The 1/4" ferrules should be available from many sources. ebay for instance.

Re: Fuel Inlet Fitting?
 

The one on the right is what everyone sells now. I doubt that the one on the left is made anymore for lack of demand.

Re: Fuel Inlet Fitting?
 

With respect Mart, What would make you believe that a part that was made specifically for a job would be inferior to some off the shelf part?

Re: Fuel Inlet Fitting?
 

So basically this is a compression connection with a nut and ferrule?

Re: Fuel Inlet Fitting?
 

NAPA has them. Weatherhead 59X4

Re: Fuel Inlet Fitting?
 

Well Bob, I thought I was in luck with that part number but my local NAPA store says they don’t stock it and can’t get it. If fact when he enters it into his computer he comes up empty. He says it’s because they don’t carry fittings anymore (he wasn’t all that eager to help.

Re: Fuel Inlet Fitting?
 

Ford used the A-9243 fitting for all the applications as far as I know. They were listed for 1928 to 1948 but may have been used later. They are kind of like the smaller fitting Ford used for distributor vacuum lines clear up into the early 60s. Those types were made to be a one piece compression fitting.

Re: Fuel Inlet Fitting?
 

I called him back and asked to look up Danfoss 59X “4” and that came up as a good number. Thanks Bob

Re: Fuel Inlet Fitting?
 

Do you remember if they were indeed a one piece fitting? What I have appears to be one piece but the ferrule is longer and extends deep into the nut. It is tight enough that you cannot pull it apart with your fingers. You can look inside and see the seam where it terminates.

Re: Fuel Inlet Fitting?
 

The only ones used by Ford on the production line were the type with a separate ferrule. The integral type only pinch the pipe on the end of the ferrule. In other words only one clamp onto the pipe. The old generic type pinch the ferrule in 2 places.

The integral type are ok but if available I prefer the old type. You can buy the ferrules separately and reuse them indefinitely.

Re: Fuel Inlet Fitting?
 

With respect again Mart. The ferrule is NOT only 1 compression point but 2. If you will just examine the picture carefully you will be able to see. It compresses the ferrule in two places just like a free ferrule. I could take one apart to show you but they are hard to come by and I do not want to waste one to prove the point.

Re: Fuel Inlet Fitting?
 

No probs. It just comes down to personal preference. I would hope they might be available rom somewhere for less than the price quoted there, though. I used to buy a carb to fuel pump pipe that had a fitting on each end relatively inexpensively from Mac's just to get the fittings. The pipe was junk but the fittings were good.

The separate type nuts and ferrules are available from Model A suppliers.
Part number A-9243 or A-9243-B if you want a 9/16" hex.

I would imagine Michael at Third Gen has the them too. He's on this forum.

Re: Fuel Inlet Fitting?
 

I find them at local NAPA. Called FORD fittings Newc

Re: Fuel Inlet Fitting?
 

The one piece fuel line fitting was two pieces pressed together to form the one part. Only one end pinched down on the tube while the other allowed some movement. The separate ferrule type would pinch the ferrule down onto the tube which would allow the nut to turn independently until tight. Both are compression fittings but both are not designed to be used through a lot of removal and reinstallation cycles due to the slight movement of surface metal at each cycle. They are only good as long as they seal the joint without ruining the threads by tightening them up too much.

Re: Fuel Inlet Fitting?
 

I don’t know, you haven’t convinced me yet. I include a picture for your examination. The nuts are identical. The only difference that I can see is the ferrule for the Ford designated fitting is longer. I believe the nut will compress both ferrules the same. I have to add that it is with GREAT hesitation that I openly disagree with rotorwrench on ANYTHING. LOL

Re: Fuel Inlet Fitting?
 

I gotta tell you guys that I just went out to my shop and did an intensive and scientific test to see what I could determine. You can start giggling now if you wish! I took some new 1/4” copper tube and tested a regular nut and ferrule and the “Ford designated” nut/ferrule. I do not think the outer side of the ferrule on EITHER combination does much of a crimp/squish. Like my dad who was born in 1895 would say “Put that in your pipe and smoke it!” Has any of you other old timers heard that saying? I am finding this thread quite enjoyable. LOL

Re: Fuel Inlet Fitting?
 

Both of those nuts are designed for the captive ferrules. The proper nut for the separate ferrules do not have a stepped bore. The bore is a 1/4" (with some clearance).

I think we are lucky that Mart wasn’t the opposing general in the Revolutionary War. Pick up your marbles and go home Mart! LOL. No offense meant. This has put a big smile on my face! Life is good here.

Re: Fuel Inlet Fitting?
 

I bought a couple from NAPA NOS, dead inventory, don’t sell fittings anymore kind of thing. Thanks for the input guys, very helpful.

Re: Fuel Inlet Fitting?
 

My NAPA interactions have changed some in the last few years.

Re: Fuel Inlet Fitting?
 

Every day is more water under the bridge since Ford built this stuff. Availability seems to go in waves. Back when I was young, the Ford dealers still had some old stock on parts but it dwindled till reproduction stuff came into being. I thanked God for Hemmings Motor News back then. Reproduction stuff has gone up and down in quality more than I like to remember. The fact that a fair amount of reproduction stuff is still available has been what kept the hobby going all this time. I just hope it keeps coming. A lot of stuff has come and gone for now at least. I just hope nothing is gone forever or it will make it hard to keep the old Fords on the road. I imagine that some of these old cars have been restored several times.
