I’ve added some pictures of both of the fuel filters. One is missing the gas cap, but that’s the one that goes to the existing tank; I forgot the cap at a gas station somewhere in Kansas. I was wondering how switching between the two tanks would be handled as well. There is a toggle switch on the dash that we disconnected because it currently didn’t go to anything. That might have been the toggle switch for the fuel. There is only one fuel gauge on the dash. I have included pics of both fuel fillers and better photos of the space near the filler that doesn’t go to a tank; there’s clearly plenty of space for one. Looking at the existing tank (pic also included but kind of hard to see), it is definitely not collapsed on top, but it looks like it would hold 17 gallons. Maybe? I’m really not sure!

I’ll get under there and take those pics when it dries up in a few days. For now I can tell you that when I filled the existing tank it would only take 10 gallons at the pump. The fuel filler that is between the door and rear tires (in pic) is the one that’s missing. I do have a gray and black tank at the rear of the vehicle. My fresh water tank lives under the dining area in the coach. Yes I use all of them. Thanks!

Hi Linda! There are two fuel fillers (see pic, 2 squares on side of RV). One leads to an existing 10 gallon tank (towards the forward part of the vehicle) and the other leads to an empty space where the 17 gallon tank used to be (towards the back of the vehicle). Check out the other pic, you can see the cut off black hose where the fuel used to come through to the tank (just below that blue zip tie). We think the yellow hose was a vent hose (?). there is plenty of space there where the tank used to be for a replacement. Now, if I could just figure out what tank and other parts I need to get… Thanks!

Hi there! I purchased a 1987 Toyota Itasca 19 foot a few months ago. Drove it from Portland, OR all the way to the NC coast with only minor problems! Woohoo! However, upon our first fueling up, the front tank (about 10 gallons) filled up just fine, but the back tank, well... apparently there IS no back tank! Gas dumped all over the ground. Looks like a previous owner removed it. Oops. So, I made the whole 3,887 mile trip with only one 10 gallon tank. I would LOVE to replace the back tank. It is my understanding that this is the main tank, and I was driving with the auxiliary tank? I know I need the fuel tank, sending unit, and fuel pump housing. Does anyone know WHICH tank I need, and where to find it and the other parts?? Or the best way to find out? My searches so far have only turned up a bunch of maybes. Thanks in advance!

This is very true! They were thinking it might potentially help create more stability. Thanks for the info. Live and learn! Or better yet, ask questions and learn!

Dang, never thought about all that! Thanks for the insights!

Thanks for the info! Any idea where I might go to do this, or at least inquire further?

I am new to this Toyota world and I'm loving it! I just bought a 1988 Toyota Itasca, 19 feet. It's in pretty decent shape, but I am doing some improvements. It has pointed out that I might want to consider going up in wheel and tire size. Has anyone done this? Does it make sense? What do I need to consider? Thanks!
