Does anyone know what the size of the stock fuel line is on a '84 MOnte Carlo non ss from the tank to the fuel pump? Either 5/16or 3/8 and if it is 5/16, what is entailed in changing out to a 3/8 line to get more fuel to motor??? Thanks in advance.
On my 307 Olds Cutlass it's a 3/8'' line. I'm replacing it now to swap to TPI. If you are not doing a body off then just fab your own lines. You probably can't get all the old retaining bolts out due to the body being in the way. I just removed all the retaining bolts I could and pulled all the old line I could out. Then just run new line as reasonably close and use the old retainers to hold it in place.
