i got a wiand intake, i forgot which one exactly, and i have a 4bll holly carb, 600cfm. i was looking at doing the swap today and i notice the fuel line than runs into the 2bll has a big connectting nut to the carb like a 1 inch nut that connets them. and its a metal line. the holley doesnt have it so how do i set this up to do the swap? this is on a stock 69 350. :clonk:

do i have to get a new fuel pump that will fit the the fuel line to the holley?

No, you do not need a new fuel pump. Easy way to do this is to cut the steel fuel line off, cut off about eight inches, get 12 inches of 3/8 inch rubber fuel line, four hose clamps an inline fuel filter, and a fitting for the holley carb for 3/8 inch fuel line, put about a four inch length of fule hose on the steel line, clamp it down, then put the inline fuel filter on clamp it down, then run how ever much of the fuel hose you need to the carb.

i was thinking of that, didnt know if i could do it though, thanks alot bro!:thumbsup:
