77olds

I bought a new fuel pump for my 403 in my 77 cutlass. A Carter M4871 it says the outlet is 1/4-18 npsf. My hard fuel line is not that. Anyone know the part number I would need for fuel line. I running a quadrajet also. I chose the Carter because it had highest gph.
thanks, Derek

olds 307 and 403

I have bought a couple of these pumps in 2 and 3 line versions, I bet that info is wrong, it will be a 3/8" outlet like stock, both of mine were.
