Yes.
You should not need a reducer. The OEM Mercury/Quicksilver Primer Bulb will accept 3/8" on the inlet side, and 5/16" on the outlet side. Straight-shot from there to the fuel pumps inside the cowling (use no additional splices, reducers, connectors, or hoses).

No way to bring fuel line through the rigging hoses?

Only other option is to move primer bulb outside hull (not ideal, but might be less restrictive).

Is there anyway to change fitting on pump to 3/8"?

Not that is recommended. The pump body is a fiber-plastic material- hanging too much weight on a fitting at the pump can (and does) cause stresses that fracture the pump body.
