73 340 Fuel Pump to Carb Line!

[Pale340]

Hey all
What size was the line from the fuel pump to the Thermoquad from the factory? I have not ordered my pump yet and I am seeing 5/16 for 64-76 A body and 1/2 for 73-76 A body. If I have too I could go dig out the Thermoquad from the storage, but I am hoping someone on here just knows. Thanks.

5/16" I believe.

99.8% sure that it's not 1/2". It's 5/16".

5/16 factory small blocks and big blocks too.

The fuel line is 5/16" the inverted flare fittings are 1/2".

Thanks everyone for the replies. I will order the 5/16 inlet and outlet fuel pump.

Let me suggest a Carter M6866
While you are at it, get yourself a new fuel filter.

This is the pump I got. 15 bucks off Amazon due to "damage"

I also got the fuel filter, but the hoses with the filter suck...

Pics of damaged box and pump... the indent on the top gold ring is on both sides, so I assume it comes from the factory like that...
