I getting ready to install a new fuel tank and noticed the tank unit uses a 5/16 line. Would this size be OK for my combo? I figure I have about 350 horsepower or so! I don't figure on doing any future upgrades to the engine.

You have the wrong sending unit - you need the one with the 3/8" tube. What size is your main line from the tank to the fuel pump? :)

It's 5/16 all the way I think. I'll check when I get home! Car had a 307 2 bl originally! I guess I should do it right and get the unit with 3/8 and plumb it to the pump.
