Question for those that did a 2.8 to V8 TPI swap
I'm doing a v6 to a 350 TPI swap and was wondering if I will have to change the fuel lines, I know there on the same side but is the v6 a smaller diameter than the v8 ones? Also is the v6 fuel pump the same as the v8?

The fuel pump is different so you will need to swap that out. the fuel fittings/size coming of the frame are the same as far as I know, but the flex lines are probably longer. If the donors are ratty, NAPA can make new ones for under $40/pair

actually if u have the 2.8 mpfi the pump should put out 40-45 psi. i used my stock 2.8 pump for my v8 swap and it worked fine. i tested 42psi at the rail.
