I had a new gas tank installed and the filler hose was a riggy job by the installer. They have since gone out of business and when I pump gas it backs up. I have two 90 degree galvanized elbows and some hose that I am told is gas hose but it is already cracking (less then two years old). Advance Auto doesn't sell this type of hose and told me it's a dealer item.  Where does one find a dealer item for a 73 motorhome???

I got my short hoses from "Carquest", NAPA should have them also.

Most fuel filler hose is available in 1-1/2" and 2" diameter. It's usually considered to be marine fuel tank filler hose and is readily available through marine supply stores or larger auto parts stores. Fleabay also sells it.

It sounds more like you have a venting problem.

Fill and vent tube were laid out without thought on my 83 Itasca..!!
The fill inlet was almost 5 inches below the top of the tank (14 inches tall) and the vent line was nearly 3 inches down from the top....
Needless to say after the tank was 2/3s full the spitback started and filling was shall we say "rather slow"....
Now I know full well there should be some room room for expansion BUT 5 inches is NUTS.....Those design engineers should be horse whipped at the least..

NAPA carries fuel hose.
Also, most places that service big trucks will stock it as well.

Two 90 degree elbows?? That might be a problem. Mine has two sections of hose about 6" long from the filler to to the tank and no elbows. I have a 40 gallon tank and a 20 gallon aux tank both mounted on the passenger side with the filler just behind the door. Are your tank(s) mounted this way?

73 Indian, my two tanks rotted and the tank switching valve didn't work. So all of that was removed and I got a 50 gal. poly tank installed. Everything was free since I had one tank repaired for 350 and that didn't work so the guy offered to replace them both and install the new one...

That being the case if it is a venting problem it would not take much to install some type of vent valve or a fitting for an auxillary vent hose.

From what I see it has retained one of the filler necks with the vent port built into it. I hose comes off of it and I believe it connects to the tank somewhere...

Do you really have 2 - 90 elbows in the large filler hose?

As shown in the Dodge MH Service manual, the small hose is a filling vent tube that connects to the top edge of the original fuel tank.
For a chassis that was built afrter jan 1 1973, Dodge added a Evaporation Control System. The hose from a charcoal canister (passenger side frame rail just aft of radiator) was connected to the front dome (left dome assembly in picture below). The right dome (B) below is the fuel sender/pickup tube.

Yup that is what I am thinking. It goes back to the tank. I am not sure how it goes there but when I get the unit back from getting the radiator fix or replace I will check. Before I dropped it off tonight I took some pictures. They didn't come out to good but I will post in about 15 minutes...

If it does in fact connect back into the body of the tank it's defeating it's intended purpose which is to vent the pressure out of the tank.
I'm looking forward to the pictures.
