Let me go a step further...Brass Barbed fittings, Brass/zinc head units, Teflon tape, and NPT fittings of any kind have no place in a 60 PSI efi system whatsoever. I can't believe these "tanks" units are as popular as they are w/o anyone taking note that modern ethanol blend gas EATS brass, Zinc, ETC., and that NPT is NOT an acceptable form of sealing 60PSI of corrosive modern fuel. Perhaps I'm nuts for thinking that an anodized aeromotive or holley pump assembly/head unit is worth the extra $, but I've seen what modern gas does to zinc/brass over time. no thanks
