I know some of you folks mentioned you have a 60 gal. diesel fuel tank on your 92 30' Breakaway's. Is it possible to have a 40 gal. tank? I ask this because I asked this question before and ran out of fuel in Yosemite the other day. A reputable mechanic said I was out of fuel. He said he put 9 gal.s in for me. I went to the gas station and it took only another 31 gal.s for a grand total of 40 gal.s. SO Where is this 60 gallon tank this breakaway is supposed to have? I can't start to tell you what a $$$ nightmare this was.

One way is to look for the ID sticker on the tank. Mine is rated for 70 gal. on my gas Regal, but it has a 10 gal. reserve yielding 80 total. I had problems even filling mine to half full because of stuck fuel vents which I blew out with compressed air.

Thanks Eddie, I'll crawl under and look tonight.

So I found the only identification plate without removing the diesel fuel tank. Can anybody translate what the capacity of this tank is by looking at this information?

4005139
0234-HH1
01 92

So I entered my tank dimensions here:http://www.ookingdom.com/metric/dim-to-capacity.html
And came up with 60 gal.s....still don't understand why it will only accept 40 gal.s..
Eddie?

Does it seem like I'm talking to myself? Feels like it..

Nope you aren't talking to yourself. You know there are over 1000 people a week visit this site and never register or leave a post.

Let me say this, I have come to the conclusion that for some reason Barth never got their fuel systems down. On my 85 gasser I have two 40 gallon tanks. But now someone said I have one 30 and one 40 anyway. Unless I have the rear tank empty I can't put fuel in the front or it will over flow. But, if I have the front full I can only put fuel in the rear one slowly. Which brings up an idea for you.

When you fill up the tank do you stop when the nozzle clicks off? Try pulling the handle back very slowly and drip the last 10 gallons in. If this is the case, then I am guessing that your overflow is blocked. You have to be able to displace the air in the tank. As it fills up there is less room to displace the air in the tank and since you are perhaps putting fuel in full blast there isn't room for the new gas. Does this make any sense??

If it won't take more than 40 gal., it suggests a vent that reaches down below the fuel level, and prevents the tank from venting once the fuel reaches it. Let the fuel settle for a few moments, and try topping it off.

I had two Dodge vans over the years, that would take 5 to 7 gal. dribbled in after the hose shut off. Took forever to fill, and I never did find out the cause, but it had something to do with failure to vent when the fuel reached a certain level.

Had a similar problem with a fwd GMC motorhome, though not so pronounced as with the Dodges. I replaced all the fuel lines on that one; seemed like yards and yards of hose. Had to drop the tanks to do so (I was younger then). Fuel no longer ran out on the ground when I filled, but it didn't cure the slow filling at the top.

Dave chimed in while I was typing my previous response. My GMC also had two tanks, with similar results.

Olroy, is that cool or what? We must be on the same wave length. OK, it's exactly 11:43 and 12 seconds Minneapolis time, what are you thinking of NOW. Naw, this can't work, there's no way you were thinking I need tires on my Toyota....

Didn't work, Dave, I went beddy-bye right after my last post. I did worry for awhile about the bad tires on my grand- daughter's V-dub, though. Close, but no cigar.

There are 2 plastic vents toward the rear of the fuel tank with rubber hoses running to the tank on mine. I blew them out, but you could replace them if the diaphagm is stuck. I would check the vents thoroughly before dropping the tank.I also dropped my tank to replace all of the lines and look for trash. If you drain the tank almost completely, it's not that bad of a job. My 80 gal. tank only weighs about 20 lbs. Good Luck

Hi Everybody and thanks for the input. I'm relieved that I do have a posssible problem as this was really baffling. I did take someone's advise and try to slowly add fuel as the foam went down. But I thought, "this will take forever!" So now I know....
I learned some interesting tow information I'll post where everyone can see...

Did you try letting your wife fill up your rig?

I have a 93 Breakaway with a 60 gallon tank (They all came with 60 gallon tanks). The first forty goes in quickly:40 to 50 takes an additional 5 minutes; 50 to 60 takes real...REAL patience to get it in. The problem is that the fuel fill line is alomost horizontal between the top of the tank and the filler neck, and Oh yes it goes in the side of the tank not the top.

Yes, you do have to wait for the foam to go down and it does take forever. So if you are just going 400 miles or less just fill it up till it shuts off, but if your going a long way be patient. I fill it up and go 500 miles and still have some left. For what its worth I get between 10 and 13 mpg towing a Honda CRV.
You can do it but it takes time. I've learned if I'm going on an extended trip I take the time. That extra 10 to 15 gallons equals 100 to 150 miles.

Thanks Eric. This definitely answers all my questions. Have you attempted to resolve the problem?
