fuel lines

[fleetimus]

I am getting ready to run fuel lines.
1) Two tanks into one fuel/water filter, no switch.
2) Is 6an big enough for 2 600 Edelbrock, possibly two 750s?
3) the fittings on the tanks are 1/4" pipe thread. Will 8an feed enough from that small of fitting if I wanted to run 8an instead of 6an??
4) Do the fuel lines need to be equal length??

From the fuel pump to the carb -6 is ok you can push better them pull asumming you are running a mecanical fuel pump.Run -8 from the tankes to a Y and -10 to the pump .You will want as much volume in the lines as you can get no matter the bung hole size.

Thanks Jake!!
How is the weather back there???

You've got to be careful with those 1/4" tank bungs! When I took my tanks out, I discovered that the pick-up tube that connected to the bung was closer to 1/8" id. I replaced the pick-ups with 3/8" pipe!
That would be a really lousy reason to burn down an engine!

I mostly agree with Jake, and if you still have a restriction in the tank - you can fix the tank and the rest of the system is done.
Only thing I would do differently (and I'm no expert) would be to use a -8 out of the pump to where ever you are going to split for the two carbs, then -6 to the carbs.
Probably should have asked how much horsepower you plan on, as this can help determine what size pump, lines etc. But I think I would still go a little bit big on stuff (it won't hurt) in case you decide to step up powerwise later.

Desk Top Dyno says 800hp

Fleet,
Take a look at this site

BTW, has anyone used the Edelbrock 160gph electric fuel pump. I just found it in the Northern Auto Parts catalog. Says it is manufactured by Essex Industries and has 1/2"NPT inlet/outlet.
Just wondering if they are a reliable pump.

Maybe This Will Help... I Ran Two Imco Stainlees Tanks On My Old Challenger. The Tanks Had 1/4" Bungs. #6 Lines To The Center Of The Transom. Through A Filter / Water Sep. #8 To The Mechanical Pump. #8 To The Carb. Single 950 Hp. 600 Ish Hp. I Ran It Long And Hard W/ Out Ever Runin Low On Fuel.
My Cp Tunnel Is A 1 1/2 Gal Imco. #8 To The Hilborn 150a Pump. Two #6 Lines To Each Carb. 1150 Dominators. Each #6 From The Pump Splits Into Two Seperate #6 Lines For Each Bowl. 914 Hp...
I Dont Think You Will Have Any Problems Feeding Those Carbs W/ #6 From The Tanks, And Even # 6 To Each Carb... But Like They Say.. Cant Hurt To Go Big... Good Luck Dude.

Hey Tim, Run as big as possible from the tanks to the regulator. I use #8 or #10 and no problems........Take out your 90* and pick-up tube sometime, you'll be surprised at the i.d. size..... .250" or smaller in the tank. I have some on our shelf, check them out! We drill them and solder new pick-ups.
Run your regulator as close to the carb as possible and use a guage. Have your passenger read it at WOT and see how much you drop....You'll be surprised here too! Here's one way to do it.......Doug

True that PC Rat.-8 to the distrbution block.
Tim the weather was 75 it is teasing us for a few days.
Jake

-6 to the float bowls but I would run a -8 from the pump to the regulator.
Forgerd 90's should be avoided if you can. http://www.sweetperformance.com/cart/images/1fa54540.jpg
A bent tube hose end will flow much better. http://www.sweetperformance.com/cart/images/1d077960.jpg

SuperD you selling the Clay Smith pumps now with the bottom in and out lets.If so I would like to burn up some cash for one.
Jake

[superdave013]

I have the pumps but don't have that bottom. I just get them from Jegs.

[Jake W2]

SuperD what about the forged 45 you think they are restrictive?
I will PM you on the pump.
Jake

[superdave013]

I think they are not as bad but worse then a tube hose end. Sometimes with the space you have to work with ya gotta do what ya gotta do though.
The cost is pretty close as the forged adapters cost way more then the straights do.

[Jake W2]

Rio the concept is the more gas volume you have in the lines the better when you have side tankes.They suck, they all ways draw from one side faster than the other most older ones have small bungs and the top feed ones talk about great ideas. :jawdrop: That is why I went to a T tank.

Dave, with all of their talk about -8 or -10 hose, wouldn't think it would make any difference if he's trying to pull or push through a 1/4 in fitting in tank. System will only flow as much as the smallest orifice in the system allows.
just my .02
Rio
But there are 2 tanks and both have 1/4" fittings. The area of both combined won't be to bad.
