5.3 engine with return style rail

this is the sending unit.. Dorman 692-056 which is listed for an 88 chevy truck (suburban). the big line on the left looks like it runs to the fuel tube that has the fuel cap. 2nd line (big line) is the feed line that runs to the fuel filter, then to big line on the fuel rail. 3rd line is the return line, small fuel line on the rail runs to this. 4th line on the end is just a vent hose?

also trying to see how to connect an-6 hose to these lines. will be using the stock fuel filter. are the threads on that 16mmx1.5?
