Fuel Line for Flathead 2 Carb setup?

What fuel line with which inner dia do You guys use for Your Flathead 2 Carb Setup? I have a german block, Eddie Meyer fuel divider valve and an electric fuel pump with pressure regulator. Thanks!

 

I use 5/16 inch. Make sure it runs uphill all the way to the carbs.

(I have replaced the cheapie regulator in the pic with a Holley)


.

 

My Studebaker came with 1/4" lines with no problems on a mechanical pump but I have since changed to 5/16"

 

Here's how I did mine. 5/16' from the pump to 1/4" into the carburetors.

 

You don't say which carbs you are using, but usually keep the pressure low-2 1/2 lbs. You may want to put an in line presure gauge on your car to monitor pressure. Regulators don't always work the way you may like. Good luck! Bob

 

1/4 steel (pump to 97's) .... workin fine

 

5/16" on my dual strombergs 97's holley reg. and 2 1/2lbs

 

The HAMB rules through guys like You! Thanks a lot!!!!!

 

When You guys use an electrical pump, do You have a line back from the carbs in gas tank, where the fuel goes when the floater in the carb is closed?

 

No return line in mine. When the float closes the inlet, it just stops the flow.

 

Not on mine either. I do have a regulator in the line set at 2.5 lbs though.
