There were some questions about "pooning" a fuel tank so here is the pic of the vent tube tail that I cut off from my tank. Having done this allows me to fill up to 39.5 gallons every time with no shutoff until the end.
I believe the manual states that the tank on mine is 29 gallons and today I put in 35 gallons before the auto shutoff kicked in, and the gas light had only been on for about 10 miles. I usually fill up before it comes on and i usually get 32-33 gallons in.
Do you think that overfilling the tank may disrupt the fuel sender.
I had a Mazda B3000 that my wife always toped off and with 25,000 miles on the truck the fuel guage would read all over the board. The dealer had to replace the sending unit and the pump ($500.00 covered by the warranty). I remember going in to check on the truck and thy had the entire bed off instead of dropping the tank. When we picked it up the idiots did not plug the tail lights back in and I almost got rearended a block away while pulling into the gas station. They also put the bed on crooked.
Redneck, you better find a new service station - QUICK. Somebody is fiddling with the meters and stealing your money. I have yet to figure out how to get 10 pounds of crap in a 5 pound box...
CWB, how much time did it take to drop the tank, remove the sender and work your way in to cut that off? Is it something you can start and finish in an afternoon? I'm tinking about doing this in the short term to speed my fillups, but have kinda resigned my self that I really want to go to a 46gal tank on my SB.
Yes, absolutely. It took me about an hour. I ran the truck dry and then did it. I have the quick connects on my fuel lines so it was pretty easy. When you pull out the tank there are some mods you can do to the sending unti as well but I don't have time right now to type them. Key things is to be really careful with the pickup or you will bend the float. Also the tank has a big black ring on top that hols the whole thing in place. It is really easy to get off but when you go to put it back, put it in the microwave for 40 seconds I think. It's not enough to melt the plastic or anything but it gets hot enough so that you can get it back on. You are not trying to get it hot enough to be pliable, just hot enough so that it expands. It will go on MUUUUUCCCCHH easier. Also, make sure that you use a tubing cutter for the vent, not a saw or something else that will leave filings in the tank or you will have to clean them out so you don't clog the pickup or your motor.This will work out your one shoulder pretty good. Have fun. It is nice to see the fuel climbing the filler hose before it shuts off.

I have filled it up at 3 different cheverons and 2 shells and it always gets 32-33 gallons in it if the guage is a little below a quarter when i fill it up.
Uhh Redneck, are you sure you've got the 29 gallon tank?? The most I ever filled up was 33 gallons, and this was after my truck had run out of fuel while pulling into the gas station. Fuel was pooling at the filler neck, and I had to wiggle the truck to get it to suck down into the tank. No doubt, that puppy was FULL.
That 'splains it. 32-33 in a 38 gal tank. Mine usually clicks off at around 24 and I massage it to take the last 5 or so gallons, most I've ever squeezed in was 31 and it wuz bone-a** dry...
Forgive me if this is a stupid question but isn't there a suction tube running from the fill tube of your gas tank thorough a charcoal filter and into the intake maniflod of the engine, thereby letting a sealed nonvented gas tank funtion. I seem to remember on Click and Clack that topping off your tank after auto shut off can lead to raw gas entering the filter, distroying or plugging it which would cause emission system backdown and a high vacumn to be built up in the tank, as the gas is consumed, causing engine stall. If overfilling a stock tank does this, what in heavens name would "pooning" do with all that extra gas sloshing up the fill tube? Hmmm?
What we're talking about is clipping the factory tank vent tube to aloow you to fill it to the top quicker. The vent tube traps air in the tank and forces fuel up the filler neck to click off the filler doo-hickey. You're about 5 gallons short of a full tank, this lets you get close to full without trickling fuel in - not over filling the system.
Gosh, I've been topping mine to the opening of the fill spout for months and have had absolutely no problems, except being able to drive an additional 60-75 miles compared to stopping when the nozzle auto-stops.
