6AN-8AN fuel line Earls, Russell fittings?
Guys, wonder what's your preference on fuel line fittings and the size from the fuel pump to the carb. Some use 6AN and 8AN line with either Earls or Russell fittings.... photos of your fuel line would help also...Thanks :seeya

I have used them both on my car, and they both work just fine. The size depends on how much fuel you want to flow. I would say read up on fuel line tech articles by any of the fuel fitting manufacturers, and try to stick to the same size line from tank to carb to avoid having to throw in lots of reducing fittings.

Personally I like Aeroquip. They way their fittings are designed are far superior to Earls, Russell, and even Goodrige. Goodridge in my opinion being the worst!
As for size. If you are running a mechanical pump up to about 100 gph you can easily get by with a -6 or 3/8 line. 100 to 150 a -8 or 1/2 line would be better, and a -10 line from 150 to 200. Return lines are ussually sized one size down from the supply line You'll always return less than supplied so the extra volume is not needed. that is if you are running a pressure bypass rather than dead head regulator before the carb/fuel injection.
I am using Aeroquip's blue socketless hose and brass fittings which I purchase from Speedway Motors http://www.speedwaymotors.com. The hose and fittings are a little chaeper than the stainless braid and are just a durable, if your not going for the cool factor this is a good cheap alternative. For long runs i like to employ aluminum tubing to run along the frame. the tubing is cheaper per foor than the hose and russel has nice ferrule type tube ends that don't require a special 37 deg flare tool.
Hope this helps, any questions email me.

:iagree: I only have aeroquip and xrp fittings. Occasionally I will use a russel adapter but no hose ends, earls I don't use at all. There really is quite a difference in quality.

I have had friends with race cars have BAD expireneces with Russel fittings, the "grab" of the hose is not very good although they are easier to assemble than other systems (Russel is now owned by the Edelbrock Corporation after Dave Russel went into bankruptcy and Wells Fargo bank sold the company to the highest bidder.) Russel may be OK for low pressure fuel systems (5-10 PSI) but, I wouldn't use this stuff on an oil of fuel injection system! (their system is based on 1930's technology.) XRP is one of the best and I like Earls and Aeroquip also (Earls is now owned by Holley and may start to suffer quality concerns but has never let me down so far!) I use -10 or -8 to fuel pump and -8 or -6 to carb from pump. EFI gets a -8 feed and -6 return line for all motors up to around 500HP. I also use the Carter NASCAR mechanical fuel pmp and not the standard street/strip or strip stuff! The NASCAR pump is a far better design and is set to 7psi so there are not needle and seat problems like with the stip pump and it's excessive pressure! My car runs low 12's with just a mechanical pump, NO ELECTRIC!!! but, DO use a lightweight fuel pump pushrod in the motor (Melling, Moroso, Comp Cams, what ever!) or you will "kill" your mechanical pump at high revs! over 6000 RPM.

I have user aeroquip, earls, russel, and summit and I really cannot say I saw a big difference. The color varies a little, but I usually buy the cheapest one that summit has in stock :cheers:

I just bought a SS braided oil pressure line kit. It came packaged as AutoMeter? :confused: Wonder who produced the fittings in the kit? They're 3AN.

I have assembled lots and lots of hoses, I have them on my dry sump pump, tank, fuel system, heater system, cooling system (bypass and the large radiator lines).

Just 5 minutes ago mine looks like this.

Re: 6AN-8AN fuel line Earls, Russell fittings? (73jst4fun)
I just did two weeks ago. What a PITA to figure out the fittings. This is what I used from Summit. I have a new stock fuel pump and a Holley 4160 single feed. I used Summit full flow hoses. They actually sell a carb kit for the 4160. The carb hook up was easy... the fuel pump killed me!!! The hose was a -6AN and the pump hook up was 1/4" pipe thread. Russel does sell this adapter. However, the pump to motor mount is kinda tight. I needed to get a 90* block adapter to route back up so the line would clear. I will post pictures when I get home. Let me know if you need more on this topic... It drove me crazy :crazy: :crazy: :leaving:

The stock fuel pump is 1/4" NPT? I didn't realize that it was that small. Good thing you said something. I was going to order a bigger fitting.

TT - I went for the metal flake blue engine block, water pump, pulleys, goose neck. It's not clean by any measure, It's to go out and have a good time in.
my 79 L-82 fuel pump is 3/8th input and output with a small 1/4 inch fuel pump to tank return line. So I ran steel braided up from the pump to comply with NHRA fuel line rules

Everything I got in the way of fuel line parts was right from
http://www.summitracing.com They are about 10 minutes from my house. So if you need help with all the little parts to do something like mine I could figure out an exact parts list.
The only chrome thing that i have under the hood is that power master 100 amp alternator. I didn't want chrome. But I was in a hurry and Summit had them on some kind of sale. So with my $100 in buying points it was basically free.

Re: 6AN-8AN fuel line Earls, Russell fittings? (crf311)
Thanks guys for your imput, after looking at some fittings locally I'm going with the Aeroquip brand. Summit sells a kit Pg.55 of their latest catalog (cobra on cover) center/top of page and it come in 6AN which will work fine..... :thumbs: what about adding a fuel gauge on this system and looks like the end is capped off?(silver end)?

Re: 6AN-8AN fuel line Earls, Russell fittings? (gkull)
I got the black powermaster alternator, the chrome didn't appeal to me at all.
Say, now that IS handy that you live close to summit. I could perhaps use that some day for small stuff :)

George, "If" it was me I would cover the line from the carb to the pump with firesleeve (but then thats just me!!). ...redvetracr
