What connector are referring to? The fuel lines connect to their respective inlet/outlet tips using plastic connectors and o-ring fittings. There are no nuts/bolts for them. Could you be referring to the bolts that hold the pump and sender to the fuel tank housing? Those are 10mm I believe.

I'm talking about the plastic fuel lines that connect to the metal pipes that come out of the fuel hat. These connectors on the end of the hoses( the ones with the o-rings you refer to) are called russel quick connects I believe. I need to know what size these connectors are. I'm sure they are either 5/16 or possible 3/8. I just don't want to buy both sizes since they are probably over 20 bucks apiece once shipping is applied.
Just need the size for the return line hose.
Thanks

Good point...perhaps you should measure it yourself so you can be sure..
