I ran 3/8 fuel line with a new 3/8 sender from Vans Auto with the stock pick up. I drilled and tapped a hole in the sender then installed a 3/8 barbed fitting with jb weld as a thread sealer "no leaks" for the return line. This setup works just fine but the ideal setup would be a new baffled gas tank with an in tank pump, I believe someone is making this setup for A-bodies but it is big $$$$ and you know how cheap us A-body guys are! Hahaha
