Stainless steel brake and fuel hard lines
The body is off the 74 so I am re-doing the brake and fuel hard lines. I am going with a Holley Sniper EFI setup with an in-tank pump. This EFI requires a 3/8 supply and 5/16 return. I am not running a vapor line and I'll swap to a vented cap. I'll be using a Wilwood master cylinder and Wilwood D8-4 calipers front and rear. I don't care about keeping anything stock if there is a better way to do it.
A few questions ...
1) Does the smaller 5/16 return line cause extra work for the fuel pump at idle? Should I do 3/8 supply and return?
2) Is there a vender that sells pre-formed 3/8 supply and 3/8 return stainless steel hard lines?
3) Does a Wilwood brake setup require the brake hard lines to be run any differently than stock calipers? For example, do I keep the splitter block in the back and the proportioning block with the low pressure sensor?
4) Are there any special connectors I should use vs stock?

1) While doing my research for the EFI system, I contacted Aeromotive and asked what size return line I should use, and they told me to use a 3/8" return for up to 600hp, and that is what I did.
2) There are multiple vendors that sell pre-bent ss fuel and brake lines. Classic tube and Inline tube are two that come to mind, as well as most of the Corvette parts vendors. I can't remember which exact vendor I used (not a Corvette parts place), but I asked if they could bend up a 3/8" ss line to match the factory 1/4" return line, and they said no problem. It fit on the frame with minimal fuss, the only thing I needed to do was get frame clips for two 3/8" lines.
3) With the Wilwood D8 calipers the only difference is with the lines to the rear calipers; instead of a hard line on the trailing arm, a flex line is used. Everything else is the same.
4) Nope

go buy a set of SS lines from ''the right stuff'' in ohio?,,I bought mine there and they are the best fitting lines ive ever used,,they make lines for just about every other seller
their lines are ''double annelled'' so the bend and work just like reg steel lines
