Hey guys. I decided to go with the new Holley 4160 465 CFM to correct my rich burning 4150 original carb. I like the idea of the external float bowl adjustment and the Power Valve blowout protection. The car does not have the lumpy idle anymore and there is only a small amount of carbon at first start up and then clears up. The only modifications are to the plumbing. The new 4160 has a banjo style fuel inlet with the pipe to accept a rubber fuel hose. My original fuel line is steel with the threaded brass couplings. Does anyone know if they make Banjo style fuel inlets with threaded couplings on the clear fuel bowl end-can i get a fuel line made? It would go from Banjo inlet to the carb to threaded coupling on my clear glass fuel bowl.
I currently have a 90˚ brass elbow that comes out of the 4150-It will not fit under my air cleaner cover because the carb is slighty wider at the fuel inlet. Also I have to modify the Distributor advance plumbing going into the carb. My original had a threaded brass coupling screwed into the metering block -the new carb has a 1/8" tube coming out of it.
Thanks all

I don't have a quick fix for your fuel fitting sizes - but I have had pretty good luck at forming 3/16 brake tubing to replace the vacuum tubes. By using a bender to get smooth corners and a short rubber tube connection on each end - it can come out looking pretty clean. On second thought - I believe I have seen the exact fuel line set-up you want, sold as a bolt-on assembly from "Larry's" Thunderbird parts and others. Ask them about P/N t 9520 - I think it attaches directly to a Holley 4160 style bowl and has a steel line formed to fit over to the glass bowl style of filter.

My 4160 came off an OMC 460 V-8(stern drive) The fuel line from the engine mounted filter to the carb was stainless steel. (I still have not decided if I am even going to use it.....)
The fuel fitting at the carb is an inverted flare fitting.
I'm not looking at it right now but I think the fitting is screwed directly into the carb casting.....I think it's a fuel screen fitting etc...... You would probably have to get a different fitting directly from Holley. I'll bet they have something that will fit.
In any case, if you have not had a look at their tech info here's the link:

Holley may have something. What I have seen is a fitting (inverted flare) that screws into the carb (you remove the banjo). The problem? is that it points to the side, not to the front. The Tbird parts guys have it, it's to make a later Holley carb fuel inlet to fit under a stock 57 air cleaner.

This is what you are talking about - right? Adapter fitting has straight threads into the Holley bowl - then female 5/16 inverted flare. It has a Holley part number but ......... 
The AC filter just fits into the same place as the glass bowl version.

First of all thanks for all the input. In a nut shell the Banjo fitting is the ideal width. If the Bango fitting had a female threaded end for the gas line that would be ideal.
Right now the Banjo has a tube to accept a rubber hose. On my 4150 Carb, I had 90˚ brass elbow that comes out of the carb and then couples to my fuel line. The 90˚ elbow is kind of a chunky block and it is a bit too wide to clear the air cleaner. The reason being is the new 4160 carb fuel inlet area is wider than my 4150. An easy fix would be a rubber fuel hose, but I would like to keep it stock looking. A simple solution would be a fuel line that has a Banjo connection on one end and a threaded male coupling into the glass fuel bowl. I have looked on the internet but have not found anything like that. A tiny 90˚ elbow may also work. On another note, when using the Banjo fitting, is the fuel tube and the drilled hole supposed to line up? AZ28 the stock connection is a 90˚ elbow and then pointed down at about 45˚ to meet up with the fuel line. The fuel line is very close the the carb so it clears the stock air cleaner. With your set-up the fuel line is much further away from the carb and would not work.
Are the fuel line connections specific to automotive or possibly go to a plumbing outlet?
Thanks

Nat, Automotive, speed shop or NAPA. Forget the hardware.

I'm not clear on the question about the banjo fitting. But the nipple should work in any direction. You shouldn't have to line anything up.
The elbows usually have a good bit of meat in them. Can you grind the clearance you need out of the fitting?
Go to a good hardware store or autoparts store and see if you can find a shorter elbow. We're not talking Lowes or Autozone for this. More like the rare mom-and-pop variety.
Another idea. Since the stock air cleaner is pretty large and hides much of the carb, you can use a short length of hose to connect the stock fuel line to the banjo. With the air cleaner in place it should be very difficult, if not impossible to notice.

Hello Nat. You might find a fitting that would would work at your local Parts Source store.You know the Can Tire owned automotive supply.My local one here has a terrific selection of fittings.

Here is a pic of the set-up. The Banjo fitting just fits under the air cleaner.
