Fuel Pump Thread Size

Replacing the fuel pump on the GT6 and also re-routing with hose (R9) behind the engine on the the bulkhead.  Struck me that if I rotate the top of the pump body then both inlet & outlet connections will face away from the block and I can then use hose tail fittings (in from the filter, out to the carbs) rather than tube nuts and olives.  However, can anyone tell me the correct thread size and if this is feasible or not?  At the same time I have work to do on the tank to pump line and it seems sensible to fit a fuel cut-off valve adjacent to the tank to ease maintenance.  Any recommends for a valve that does not constrict with too small a bore size?

Thanks Pete, in which case does not seem compatible with the options available for hose tails (1/8 NPT or 1/4 NPT) through Car Builder Solutions and elsewhere.  Staying with Triumphs original design at the pump then, but is there any reason why I should still not realign the top of the pump?
