2005 3200 Open w/ Crusader 8.1 - Fuel line size?

[tyrentz]

I've been chasing a fuel supply issue and suspect the solenoid cut off (that is ahead of my aftermarket Racors); You can tell by the photo why I suspect it! it's easiest for me to just bypass it to test before replacing the whole thing, but I need to grab a coupler / barb. Does anyone know what size fuel line, and what size hose fittings are used for the fuel line that screws into the coupler? The solenoid is 1/2" NPT, and the coupler going into it (circled in orange in attached photo) looks like a reduced size, so I suspect 3/8" NPT fitting for the fuel line female fittings, and 5/16" or 3/8" ID fuel line? If anyone could confirm I'd appreciate the help.
