5/16 or 3/8 fuel lines

[wedge974]

Will the stock 5/16 fuel lines provide enough gas for a modified 318 with 350 or so HP, mild cam, mechanical fuel pump, and 650 Edelbrock carb?

I was thinking about upgrading to 3/8 lines but I do not know if it is necessary.

Any suggestions or opinions?

You'll be fine with the stock 5/16. I'm running a 360 with mechanical pump and 650 AVS edelbrock carb and don't have any fuel delivery problems. I think once you get into the big HP engines (500hp +) it might be a different story lol

Go with the 3/8 if you are able, you'll never have to wonder if
your starving for fuel.

Absolutely not necessary for your combo. You will see zero return for your money.

I use 3/8" on my 360 down from 1/2" on the race motor. Its not like a big horsepower motor ya running.

I agree, spend the money on some other performance parts instead LOL
