1995 Bounder Fuel (gas) leak

If the fuel is coming out the filler solely where the pump nozzle fits, that doesn't sound too off to me; it just means you overfilled the tank and left no room at all for expansion or sloshing. It's not wise to top off to the very tippy top; stopping at the first or maybe second click-off of the pump is appropriate (provided, of course, your filler is arranged so that it doesn't prematurely shut off when there's still many gallons worth of empty space in the tank--if it does that, it usually means the gas lines from the filler to the tank are not properly routed or are pinched or something). Besides the possibility of gas coming out, this is a good way to harm the vapor recovery system by having the recovery canister be filled with liquid gas.

If it's leaking from the hose or connections between the hose and other parts, yes something ought to be fixed: either a loose connection or a worn or damaged hose, most likely.

:h

There is something wrong about this statement..

Even IF the tank has been overfilled, it should never leak, especially not at the filler cap which sometimes on older vehicles had a check valve to let air in. Older vehicles often had a vent at the top of the tank which had a small vacuum line run up to the engine compartment to a vapor recovery tank lined with charcoal that would absorb excess fumes from the tank, that tank was way above the filler neck. Those fumes then were slowly introduced to the engine while it was running.

Newer vehicles have similar vent on top of tank but the vapor recovery system is often located near to the tank just above the tank but lower than filler cap.. This setup, you can accidentally swamp the vapor recovery system if tank is overfilled but the LEAK would not be at the tank.

Fuel systems are a "sealed" system and have been since well before the 1970s, fuel and vapors stay IN and when you use the fuel there is a check valve in the system which allows AIR to enter the tank. When vehicle is not running the check valve that allows air in must close.

Newer vehicles add to the system by checking the tank periodically for LEAKS via a vacuum/pressure test, don't get the filler cap on correctly you will get a CEL or if equipped a filler cap light..

OPs MH needs looked at to find and fix the leak which is most likely a loose hose clamp or rusted out filler pipe.
