84 Holiday Rambler ambassador/ fuel tank

Had to drop the fuel tank in the mh to replace fuel hoses and bad fuel sending unit. to my delight the tank is made from stainless steel but I noticed that there are four ports on top of tank

1. fuel supply to genny
2. fuel supply to engine
3. vapor/return to tank
4. ???? had something attached at one time but was just cut off not even capped off.

what else would need a fuel supply??? This is a carb'ed 454.

Most GM engines of that vintage have a supply line, a liquid return line, and a vapor line. The generator only requires a supply hose. Someone may have capped a line somewhere on the coach. You certainly don't want an open port on the tank as fuel vapor could collect under the rig and pose an explosion risk.

My Holiday Rambler has a fourth line, too, but it is plugged. I wondered what it could have been for, too.

I have seen those tank vents also. They sort of look like a plastic cap. At some point, I don't remember which year it changed, the fuel tank was vented to the vapor canister in the engine bay which was kept under a light vaccum via a hose to the inside of the air filter on the breather.

Check the large fuel fill tube to see if there is a vent hose used to vent air off when your filling the tank with gas. Small hose that runs along side the main fill tube.
