3/8 fuel line

[dave73]

I'm going to upgrade my 5/16 fuel line to 3/8. I have a 440, recommendations on a mechanical fuel pump part #? Where do you guys buy your lines? Also, do I need to upgrade my sending unit to a 3/8 right away or can I run it for a little while with the 5/16 sending unit? I understand the restriction for now.

@MoparDave  has gotten me my sending units and fuel lines.  I think the 3/8" line has a 1/4" return line too.

This might help:

I ordered a 3/8" line and sending unit from @MoparDave, and just made my 5/16" line the return.  Made it a lot easier to install.   

I also switched to a electrical pump and routed the main line up the firewall to keep it away from the hot block.

I can get you the lines in 3/8 and the sending unit and pump. just need to know OE steel or stainless ?

if you use a HP mechanical pump that will disassemble such as Holley or Carter take it apart & bore the holes inside as most are 1/4 or smaller internally
