I am looking to redo my fuel lines from the fuel sending unit to the corvette filter up to the fuel rail with returnless fuel rail on a 2004 5.3 in a 1992 chevy pickup originally had a 350.Right now i have rubber fuel injection hose clamped to my old fuel lines with the corvette filter in same locotion as original filter and everything works fine but i want to use braided lines.I did a search but i can't find what fittings i need to connect the sending unit to adapt to AN fitting.Are the male fittings on the sending unit sae or metric?

Thanks Joe
