anyone know what size the fuel return hose is from the regulator block back to the tank. I know the inlet is 1/2 but i forgot to measure this morning before I left for work and need to order today, thanks

I'm pretty sure the return hose is 3/8 ID.  The fuel supply and return hoses should be type A1 fuel hose.
