Fuel lines

[gagliano7]

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

Think they are 3/8 and 1/4.

The lines are 3/8 and 5 /16 but i am not sure if the threads on the sending unit nuts are metric or SAE.I found a few things on line that say the threads are M16 x 1.5 and M14 x 1.5.I just want to make sure i buy the right connectors because they aren't cheap.

Check rpmgraphics build thread. I think he has pics. Hpicamaross might have pics in his also. Speedway sells a great vette filter kit. It has the fittings with it that connect directly to filter.

I check rpmgraphics build.He connected to lines where the filter was.I am going all the way to the sending unit but they look like the right connectors.I will check out that filter kit .

Thanks
