Fuel Line - '67 L30 w/Q-Jet

[67rs327]

So while replacing the fuel lines on my '67 L30 - I apparenty didn't pay close attention to the diameter of the fuel line  from the tank to the pump (this is what I get for working on the car at 1:00 a.m.), ordered and installed a 3/8" line only to discover today when comparing it to the line from the pump to the carb - that the originals are  both 5/16". So I now have 3/8 into the pump and 5/16 out into the the carb - will this cause problems? Pump is stock. Carb is stock Q-Jet for L30/275. Stupid mistake that I'm going to correct - but will this cause problems in the short run to the the pump, carb, etc? Thanks - Chris

Shouldnt cause an issue.

Why don't you get a pump with a 3/8" output and install a fitting for a 3/8" input on the carburetor?  That way you can take full advantage of your 3/8" fuel line.  But I agree with Darrell above, it shouldn't cause any issues leave it 5/16" from the pump to the carb.
