New guy--fuel lines

[itravlsum]

New to the board.

Fuel line question. To go carb convert I should use larger line and pickup tube. Example 3/8 for 300 h.p. streeter no track. No problem. Stock line for my 86 is 5/16 with intank pump. Wonder why that fuel line works for 100h.p. nitrous shot on stock setup as venders say, but need larger line for carb. Is it that some folks bolt and go using larger pump only on f.i. Set me straight. I confuzzed.

Thanks

Carb motors use high volume, low pressure fuel lines. Fuel injection uses low volume, high pressure. Hope that clears up your questions.

Much higher pressure with F.I. carbs won't take much more than 6psi without flooding the bowls, ect.

Thanks guys.

Now next question. I need a 3/8 in tank fuel pickup line. Another board sugested making one or getting an after market one--$120. Does any older year carb car have a direct install? 85 stang pickup tube was a choice but hard to find. I will be running a mallery 110 pump.
