blazer fuel lines

i have a 72 blazer 2 wheel drive that had a 6 cyl in it. am going with a 350 now . i bought a new gas tank and sending unit. the problem is all the fuel lines to the motor are 5/16 and the out let for the sending unit is 3/8 ? would that be because the sending unit is for a v8 and the lines are for a 6 cyl ? also when i put on new lines do i need to have the double loop at mid frame that has hose on it? one more dum ass question. cant i just simplify the whole system and not have all the plumbing that goes up to the round tube at the back of the bed? thanks to all for any help.

Re: blazer fuel lines

You are probably correct on the 6 cyl & v8 sending unit. I just put together a jimmy with a v8 and just run a simple configuration. Single line no return and have not experienced any issues. Hope this helps
