fuel sending unit question?

Is there a big differance in changing a 3/8/inlet w/ 1/4" return sending unit on my 67 lemans with a/c, changing it to a 3/8" inlet w/o return line? does anyone see a problem, or future problems with it or would a 5/16" inlet work any better, or just replace it what was original? thanks for any help! Thanks Johnconfused

You should be able to replace it with the 3/8" w/o the return line, but you should change the fuel pump to the one without the return line as well. Or just put the original 5/16' one back in. The only reason to swap to the larger one would be if you are running out of fuel at WOT.
