Mechanic's Assistant: Is the fuel filter an external one, or is it inside the tank?

Two one at pump looks like oil filter size or is I should say one in line also

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Fuel pump on the boat has what looks like vacuum line or vent that not hooked to anything got in an out lines to pump and this clear plastic hose 1/8 out of pump ???

I know on my Holly you loosen that locknut and hold it while you turn that screw, except of course mine has 2 of them since it's a 4 barrel.
