need some help from those of you who have 1/4 inch SS fuel lines.

Going from 1 94 carb to 2 94 carbs, the 1 carb setup had 1/4 inch SS tube with 5/16" thread compression fittings
like to keep it this way for the 2 carb set-up

where can I get SS tubing and compression fittings that will work?? tried checker and advance,,,no help

 

Your going to need to find a machine/welding shop. Alum, copper and mild steel are all you should find in auto/hardware shops. Check this out anyways, http://www.classictube.com/

1/4" sounds small for a dual carb'd V8. I'd suggest looking into 3/8" tube.

 

thanks fot the info--But if 1/4 tube fits in the carb inlets, why would 3/8" tubing also fit?
thats doesn't make sence to me

 

I don't think 94's will cause you grief for starvation out of 1/4 inch lines. Should be plenty with a healthy fuel pump. Look at the swagelock (swagelok?) line for high quality stainless compression fittings. They are good for 600 psi or so but compression fitting such as those are not DOT rated.

 

You are going to have to have some type of manifold (unless your running them in series) to spilt one line into two.

More power requires more fuel, I would go larger than stock so I wouldn't have to replumb it later.

 

i was measuring 6 lbs of fuel presuure with my stock pump, 1/4 line with the single 94. the carb spec calls for 2.5 lbs pressure for 1 carb....
I hope this still should be more than enough pressure for 2 carbs

I ordered afree standing fuel block to split the lines
thanks

have ya checked these guys out?

 

Do you know the flow rate for the pump/carbs? your current pump can handle two carbs pressure wise, but you also have a volume difference and an extra outlet for the pressure. It never hurts to have supply lines capable of the next big upgrade.

He asked for SS, russel's fuel line is aluminum. I haven't seen much from either of those vendors in hard SS lines.

 

I'd say 3/8" line is overkill for him. 5/16" will feed a 350 hp fuel injected engine.
