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! |

Re: Carb fuel line vs. intake manifold
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. |

Re: Carb fuel line vs. intake manifold
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.
