I'm not asking where too buy fuel lines I'm asking how much I need to buy.
I also heard that the type 1 fuel lines is a different size. |

Actually, the Type 3 FI line is 7.5mm which is bigger than the Type 1 line. Even the 7.5mm is a little tight. The current recommendation is to use 5/16" regular fuel line. It is closer to 8mm and fits better with less stress on the line.
So depending on the year of your car, you might need the 5/16" stuff at the tank. Not sure about at the carbs themselves. Probably 1/4".
As for the length of line needed for a carbed car.
12" tank to tunnel
36" tunnel to metal line through engine tin
18" metal line to fuel pump
12" pump to "T"
12" "T" to LH carb
24" "T" to RH carb
so figure 10 feet of line.

John is that the same for an FI car?
Thanks

an FI car requires about 20' feet of line and it must be able to withstand the fuel pressure required for FI....

Blank is right. You need close to 20 feet for an FI car. You have return lines and fuel loops and stuff. But you only need to buy standard fuel line not the special FI stuff that they sell at your FLAPS. The current FI stuff is for modern FI systems that run 70-90+ psi. The Type 3 DJET only runs 28-32 psi and the standard fuel hose at your FLAPS is plaenty sufficient for that. I think it has a rated burst strength of 60 psi or something like that and there is a considerable factor of safety on the "rated" bust strength.
Russ can gives us all the details.
Don't spend money on unnecessary FI rated hose. Way overkill.

I have burst tested Standard 1 ply fuel line that is rated for 250 psi. It went to close to 600 psi before it failed. What they are selling for FI hose now days is 2 ply and not the standard 1 ply.
As John says, our systems are only 28-32 psi max. and if there is a pinched return hose, maybe 60 psi before the pump stalls.
The highest fuel pressure on a production car that I know of today, is a Ford at 63 psi. There is one regulator made for a special ricer hotrod package for the NEON, that goes to 75 psi. but we only make about 200 of those a year, and they are expensive, since we have to make them by hand, as our automated calibration machines will only go to about 65 psi.

I know this is an OLD thread, but hey I searched. 
Does anyone have these sectional lengths for FI cars?

No, most of us either buy a 20 ft piece, or a 25 ft roll, and make up our own lengths. This is because not everyone is running the same fuel pump, or has their hoses laid out the same.
Nice to see you're still around Annie.  How's Savana running these days?

I am still her Mom... along with a 66 Rivi, 74 type 4 and the half back still in process... Savanna is running great except for a rear axle that I need to swap out other than that life in my VW world is awesome... I am in Maui right now and driving a 67 Squareback... Oh and I was just gifted a Wolfe Pack Member Memorial bumper sticker from Drag'in Ink...

Sorry for bringing back a really old thread but....
It was said earlier in this thread "The current recommendation is to use 5/16" regular fuel line". Is this still true or would you guys recommend a different size fuel line? Also, will I be ok buying 20-25 feet of this size line or am I going to need any other sizes? |

Yes to both. Use the stand 5/16ths fuel hose, and get 20 to 25 feet of it. Also, try and find the FI style hose clamps, as they don't cut into the hose. If I remember right, you need 35 to 38 hose clamps.
