Carb fuel line vs. intake manifold
 
Short version: is 1/4 inch too close for fuel line to aluminum intake on 454?

Longer version: I swapped out my factory cast iron intake for Edelbrock Performer on my 454. I slightly rebent the factory metal fuel pump to carb line to compensate for the slightly taller intake. This places the metal fuel line about a quarter inch away from one of the intake runners. Is this going to create issues with too much heat on the fuel? Should I cut the metal fuel line near the middle and place a short piece of rubber hose to help lengthen the line? I like the mostly factory kinda look and wanted to keep the nicely bent factory metal fuel line.
Thanks in advance!

An intake runner should be fairly cool as vaporizing fuel in the carb tends to cool things off. If there is a hot spot, you could split some rubber line and slip it over the metal line as insulation.

I would keep the factory line if possible.

With the way my carbed 454 reacts to under hood heat, Id keep it as far away from any hot surface as I could. I've had terrible percolation issues.

You will be Okay.

If you want a conversation piece :uhmk:

You could put a wooden clothes pin on the fuel-line.
