Your carb is likely re-build able. Your coach is a little older (we had an '83) but carb is probably a Motorcraft, actually made by Holley but with some differences. Holley aftermarket carb listings include "not for RV use" but I'm not sure exactly why.
A re-build kit should be available based on info from a tag that should be on the carb. What I'm about to add next is a Big Deal:
If these engined bckfire, the Power Valve in the carb is likely to rupture. Then it dumps gas out hte bottom of the carb all the time, not just when it needs to. There's a kit available at speed shops that 1. Plugs the original vent hole and 2. Replaces a screw with one that has a little spring loaded check valve in it.
If you can find a fuel system specialty shop, they'll tell you they include this in their re-build process.
Pumping the gas won't help if the power valve is the problem since it's already flooding. I think you need to edit the OP to add "not" about the fuel pump, based on all else you've said. But IF your year is one where Ford used a mechanical fuel pump, it's mounted on the front of the engine a foot or so from the carb. Fuel pumps leak fuel when they fail and you'd smell it from there also. Should be a label in the driver side door jamb. Build date will tell you the model year of your chassis. RV by RV Model Year (and probably the registration info) may be one Year and the Chassis a Year earlier. This can fox you when you go to buy parts.
