Car Forum / Jeep / March 2005TJ gas tank modification question
I've seen some posts for the older (87-95) jeeps where you could modify the vent tube to allow you to fully fill the gas tank to 19 gallons. Is this true with the TJ's (1997+) also? Can you modify the gas tank that way? Any web sites/URL's that show how this is done would be great! -mike If you didn't buy the twenty gallon option, you got hosed: http://www.gottrail.com/TJ/TJfueltankconversion.html God Bless America, ßill O|||||||O mailto:LWHughes3rd@aol.com http://www.billhughes.com/ > I've seen some posts for the older (87-95) jeeps where you could modify > the vent tube to allow you to fully fill the gas tank to 19 gallons.

DC went cheap and only put one size tank in a bunch of YJ's and TJ's. If you ordered the smaller tank, they just put the fuel filler shut off vent down into the tank deeper. This 'vent' is not a vent really it is only in use when filling up the tank to let air out, then gas. When gas reaches it, it sends gas up to the filler nozzle shutting it off which implies the tank is full. The modification only sets it up like the larger tank. "The vapor canister is filled with gas?" What kind of BS crap is that? Jeeps have a check valve and an anti roll over valve on the canister line so the vapor tank cannot fill up with gas even if you roll over!!!! I don't know what they teach 'mechanics' these days, but really....

What sort of decision was that ? A 25 gallon one would have been more like it ! At least give us a decent 400 miles + range..
