GREAT BIG UH-OH, TEE-TOE!!! I did the loop trick when I put a Holley EFI on a Blazer a couple years ago, DON'T DO IT!! Or, if you do, don't ever run that sucker outa gas!!! If you run outa gas, you end up with a slug of air in the fuel line!! The only way to clear it is to remove the bypass loop and pump the air out. It really sucks. When I replaced the sender in my '68 ragtop last winter, I took the fuel tube outa the old one, shortened the business end, and drill a hole in the new sender and welded it in. When I go EFI, I'll have that 3/8" return line I need.
