Fuel filler pipes

YOu can make you own filler neck or have on made out of stainless.

As far as a tank you don't need a fuel cell. I run Hot Rod City Garage's aluminum tank. It's internally baffled as well as large outlet and return line capability. Mounts in the factory location with the factory hardware.

Best electric pump I've used is the Aero A1000.

I went with the Hot Rod City tank as well when I went back to EFI on my 5.7 swap to get the in-tank pump. Nice guy to work with and good looking piece. The main issue I've had with it though is that I can't fill it very fast. The old tank and fill neck had an inner baffle that separated the top and bottom so that it could vent better. Since the Hot Rod City tank has a small neck that you couple a fill tube to the baffle can't easily extend all the way down into the tank a bit, so it will burp fuel at me if I pump it too fast. I don't think the little vent line on the tank where the fuel pump fittings are is big enough to move the air out fast enough.
