fuel line

[Scat Pack Fever]

Hello all
I have a 1974 challenger with a 360. For some reason I ordered 3/8 fuel line from the tank to the fuel pump. My sending unit is 5/16. I have the pre bent fuel line from the pump to the carb that is 5/16. Is it an issue having  2 different sizes? will that cause a fuel pressure issue or should I just get the 3/8 line from the pump to the carb?

Should be fine

Should be fine

The only issue you may have is the piece of rubber fuel line from the sender to the 3/8" line. You will need to use 3/8" rubber fuel line and clamp it tight enough to seal on the 5/16" sender.

You're fine....Most cars have 5/16 Pump to carb lines.

I actually made this mistake when ordering my Tank sending unit, the line is 5/16 but the sending unit was 3/8 like the others said i just clamped it down and it hasn't leaked a drop in the past 2 years. You should be fine.

I'm running a 74 challenger with a 318.

I think I bought it off ebay, but can't remember. It was about 6 years ago. Not sure how I ended up with 3/8 line.

Fine Lines and Inline Tube sell line kits.  I think The Right Stuff does also.  I prefer Fine Lines.
