Tbi return line conversion

Wanted to see if someone out there could help me on a TBI return line I have 5/16 going back to the tank area I found a sending unit(guage) with 3/8" supply then the return is 1/4", opinions as to if the 1/4" line is going to be large enough or if I have to modify it to 5/16" if it makes any difference it's a stock 350 in an older vehicle. Thanks, Eric

The 1/4" return should be plenty. The return just takes excess fuel back to the tank, it's not flowing full all the time -- not unless you have a way oversized fuel pump. Using the stock pump the 1/4" return line should be plenty.
