Gas tank

My Scout leaks fuel when fueling it and I determined that the rubber hose that goes from filler neck to tank is bad. I'm dropping the tank today to replace it, any tips will be great. I'll let you know how it goes.
 
Almost as common as bulkhead connectors that go toast!

Replace all rubber while the tank is down!
 
I am loving this site, the b.bulletin was down, I searched, found this place and I am loving it. Thanks for all the help, when I need parts I will be shopping here.
 
Yep, got stuck here too, even before bb went down (nothing against bb though, great site!) :gringrin:

here's my post on the fuel tank removal, went quite well (took an hour or so), soak all nuts in wd40 or such before you start:

fuel tank
 
I hope that this thread will work for my question. I have had my tanks out before and have gone through all of the hoses. ( yes tanks, my metal one leaked and so I put in a plastic one that I had. )

problem is that the breather tube that returns back to the filler tube fills up with fuel also and then it spits it out, of course, when pressure builds up. I am having to pull the tube from the filler tube and blow back into the tank via the breather to push the fuel in and hold the breather tube disconnected to fill up.
This happened with both tanks.
Input?
 
Your fuel tank system is not venting for some reason. Is the entire evaporative emissions control system still in place and plumbed properly? Or has it been "modified" in some manner?

As you have described, it can only vent back through the filler neck...once fuel approaches the level of the tank opening, it can no longer vent.

Verify all tank plumbing for correct install and no hoses being crimped off in any manner or internally collapsed.
 
Mariposa - along with the questions michael asked you does the vent hose have a sag in it? If this hose is too long and sags it will fill up with fuel and block the flow of the vent.
 
All the evap emmisions equipment is there. I saw no need to omit any of it. I will check for a sag in the line, and proper plumbing also. Thanx, I will post what I find, maybe it will be useful to others..
 
I have what sounds like a similar issue. Ever since purchasing my 73 Scout I have to fill up the tank very slowly as service stations. I have replaced all of the hose and still have that evap thing in the body wall. A new issue has come up where I filled up the tank into the neck...the truck would idle fine but would starve for gas when I tried to drive it. After a few miles of fighting with it, then it just took off and now problems since. Could I have some sort of venting problem? Do I need to look and anything else besides what was previously recommened. Also, can I just get rid of the charcoal canister thingy or should I keep it and just cap the line. Tia
