size of fittings on fuel lines at the tank

[Julie & Lloyd on Rendezvous]

Because of a variety of problems/decisions,  we pulled our fuel tank and had a new one made.  I am having difficulty sourcing the shut-off valve which needs to screw into the fuel pick-up and then the fitting for the return.  I am missing one important piece of data - the fitting on the end of the two fuel lines - can anyone confirm that it is 1/4" NPT or if not, what it is?

thanks.
