If I have a short term need to run my coach from a boat fuel tank; About how much and what size of fuel line do I need to get?
Also what fittings etc. if I use the mechanical fuel pump, and what fittings if I need to use an electric pump?
Thank You.

8 feet of 3/8" hose should be plenty.
The connection to the mechanical pump will just need a hose clamp for the 3/8" hose.
The boat tank side will vary by whatever boat tank you use.
The mechanical fuel pump is easily accessed through passenger side wheel well. Take out the wheel well liner. And it is located
On front of engine. You will see the fuel line coming up from frame to pump.
If you jack up the frame a bit, it will allow somewhat skinny people to fit between tire and floor. Otherwise if you cant fit in there remove the tire/rim.
Careful.

To continue:
I would probably put the electric pump inline and still feed that to mechanical pump. Otherwise i am not sure what size barb fitting would go into front of the q-jet carb.
Fittings for electric pump depend on the pump. Be carful for electic sparks and gas when connecting things up.

The boat tank will sit on the front bumper and you can tie it off through the grill to things that will hold it in place. The fuel line can also go through the grill, over the top of the radiator by the filler neck and directly to the fuel pump. Just tie it off so it doesn't get into the fan.
Folks have recovered coaches using his approach and driven hundreds of miles...5 gallons at a time....

I have done it several times. The shortest one was under 1 mile. The longest one was around 300 miles with four 5 gallon cans and one stop at a station along the way to refill them.
I see no reason to install an electric pump if the mechanical one is working. It adds nothing and increases complexity of the system. Vapor lock is a non-issue because the can is located above the intake side of the fuel pump and is only about 6 or 8 feet long.
I had one short distance move where the fuel pump was questionable. So we installed the can in the passenger seat and ran the hose direct to the carb without any fuel pump.
Because the can was higher than the carb, it gravity fed and worked just fine without a fuel pump.
On carburetor high wing airplanes the fuel tanks are overhead so no auxiliary pump is necessary or installed. Fuel will gravity feed in case of a fuel pump failure. On low wing airplanes an aux pump is installed in case the mechanical fuel pump fails.
