6.0L fuel cap preference

Im looking to upgrade my oem secondary fuel filter cap to aluminium. Does anyone have a preference. They all appear to be similar in price...River City Diesel, Nuc Motorsports, Sinister Diesel.

I already have a Nuc Motorsports oil cap that I run with my Amsoil bypass filter. I'm happy with that, but I'm always looking for better - quality, value.

Looking for opinions before I purchase. Dosent have to be any of the ones I've listed here.

Thanks. Tim
